Adding Hogue Rubber Grips to my 10mm TRP Operator Longslide

After I finished polishing the chamber of my new 10mm TRP Operator Longslide, I also replaced the VZ Grips. Maybe it’s my carpal tunnel but I really prefer rubber grips on my single-stack 1911-style pistols. Fortunately, the Hogue 45000 wrap around rubber grips fits great.

The VZ-Grips that come with the TRP are very nicely executed. Replacing them is as easy as removing the two Torx screws you see on each side.

Replacing the Grip Panels

I did some digging and the Hogue 45000 rubber grips are a drop in replacement rubber grip set for Colt-Government size frames including Springfield Armory pistols. Sure enough taking them out the package they lined up just fine.

To remove each panel, you will need a Torx 15 (T15) bit and I would recommend a container to hold the screws. I like using a magnetic tray to avoid them bouncing around.

My factory screws backed out using a T15 bit and I was surprised that there was no threadlocker or much torque..
You have to love the easy stuff when it comes along. The original grips lift off the threaded inserts and then you slide the Hogue into place until the holes align. Yeah, it’s that easy.
When you go to re-install the screws, use a medium-strength threadlocker. I’ve been using the Loctite “stick” series for a while now as you avoid the traditional liquid making a mess as it drips. Would the liquid work – for sure. The stick is just convenient. In terms of torque, I just brought them down snug.

On the topic of grip screws, you have some options to avoid lost screws. First is to use a medium-strength threadlocker and another is to put an O-ring under the head of the screw. Some guys use #61 plumbing O-rings and others use 1.5x3mm Buna-N O-rings. I’d recommend one of the two vs. nothing.

The Hogune 45000 is an easy install. If you are wondering about the Wilson 47NX 9-round mags, I really like them too.

Conclusion

The pistol passes testing with flying colors – it now cycles fine, the slide and everything operate very smoothing during manual testing and the grip makes a huge difference for me in terms of comfort. Now, I just need to get some range time 🙂

Sources For the 10mm TRP Operator and Ammo

Here are some reputable vendors you can order either the 5″ or 6″ TRP Operator plus ammo:

Tuning the 10mm Springfield Armory TRP Operator To Feed Reliably

After the very disappointing performance of my new 6″ 10mm TRP Operator at the range, I knew I had two options. First, I could send the pistol back to Springfield Armory for repair or two, I could try just a bit of light polishing first. I had good reason to want to try the second option first.

A few years back, I had a Rock Island Armory 52000, that’s their big top of the line doube-stack 10mm, that had problems feeding Underwood ammo but not S&B or SIG. In looking closely at what was going on, I could tell the lip of the case was hanging on the lip of the barrel and not going in. I used a rubber abrasive Dremel bit, rounded the edge of the chamber ever so slightly and the problem was solved.

In looking at the brass coming out of the TRP during test firing, it was getting very scratched and in some cases actually nicked/gouged as it went up the feed ramp and pivoted to then be pushed into the chamber. The rounds that stopped dead and would not feed had to be tapped out with a cleaning rod. They all had a slight nick/gouge in the case where the edge of the barrel literally bit into the brass effectively locking the round in question in place.

I sure wasn’t happy at the range but at least I had a plan of attack. When I had time a few days later, I waded in to try fix the problem.

Before you ever work on a firearm, make sure it is not loaded. Be sure to check the chamber and do not have a loaded magazine in it either.

Disassembly

The 6″ TRP is a slightly odd beast. It does not have a traditional guide rod. You disassemble it just like any other 1911 by pushing the slide forward to the point the slide stop aligns with the disassembly notch and pushing the slide stop out. I don’t know of any tricks to unload the unique recoil spring system the 6″ Longslide TRP has.

As you move the slide forward off the receiver, be prepared for the spring to want to jump out so be sure to have a hold of it before you get the slide half way off exposing it forward of the browning link.

Notice the heavy bull barrel with no bushing and also the unique recoil spring. There is that stubby little guide rod and a long plug that the spring goes into. As far as I know, this is unique to the 6″ Longslide model and is not found in the 5″ TRP.

The spring system is annoying during disassembly and re-assembly but I am getting used to it. I checked with Wilson and Dawson plus did some googling around and nobody has anything to replace it so I’ll just deal with it.

The Barrel

Okay, I took the barrel and looked at the point where the steel transitions from the feed ramp to the chamber. It wasn’t polished and it was practically a knife edge. No wonder the rounds where getting torn up or even caught on that sharp edge.

This is the barrel straight out of the TRP without any cleaning or work done. The ramp is fairly smooth but I wanted to polish it more – same for the chamber but boy is the top of the feed ramp an abrupt sharp angle. No wonder cases were scraping on it and/or getting hung up.
If you look at the angles of the three types of rounds I was test firing with, the most successful was the 220gr hard cast in the middle. The S&B 180gr FMJ on the left has more of angle and the XTP on right has an even greater angle. None of the bullets were damaged during testing it was the cases. Notice that the greater the angle the worse the round fed and the more chewed up the case was.

To address this, I got out my Dremel, rubber abbrasive bits, some felt bobs and also a bit of 800 grit polishing compound.

One thing to remember up front – you do not need to take off a ton of material so use a fine grit abrasive and a relatively low speed. You want to work a bit and test until you get it right where you want it.

That’s a close up of the TEMO rubber polishing burr that I use to round over transition from the ramp to the chamber. Basically you want to get rid of that abrupt sharp edge and round it so that it is easier for a cartridge to tip over and get pushed into the chamber.
You can see the rubber that came off the bit during polishing and also note the slight rounding at the top of the feed ramp – that is exactly what we want.
Next up is to polish the ramp and the chamber. To do this I used a 10mm felt bob and 800 grit grease-based lapping compound. I’ve used Flitz in the past too by the way and it works. I like the Goodson compound due to it being petroleum based. It seems to cut better and doesn’t fly all over the place. Note, this is 800 grit and we just want to polish – our goal is to remove as little material as possible while getting the job done.
Okay, here’s an action photo. I polished the chamber and the ramp already. You move the bob around and don’t sit in one place – back & forth, up & down, in & out. Think of it this way – you are your own random orbit sander and don’t want to stay in any one place too long and remove any more than needed.
I put CLP on a 10mm Ramrodz (think of a Q-tip made for cleaning a 10mm pistol barrel) and cleaned it it out followed by a second to mop any remaining debris. I carefully cleaned the other surfaces as well.

Greased the parts that slide

When we were at the range, I noticed the action was sluggish at times. This is to be expected during the break-in/wear-in period of any firearm. What I do to help the parts get to know each other is to use an acid brush to apply a light film of SuperLube grease to the parts that slide. Not a ton – just a film. For the TRP, I put it on the slide rails, the bottom of the slide. the exterior of the bull barrel and in the slide where the barrel passes. Wow – what a difference. The slide feels smooth as glass now. I also again put a drop of SuperLube oil on the trigger, hammer, browning link, etc.

Re-assembly

Putting it back together takes some practice – re-install the barrel and try to hold the recoil assembly in place as you slide on the receiver. For me, it’s easier if I do it with the slide inverted (bottom up), hold the slide and spring with the left hand while guiding the receiver into place with my right. One the receiver is on about half-way, the spring is adequately captured. Now, this also means that when you go to re-install the slide lock, you are fighting the tension of the spring. I support the pistol on a table during this step and am getting better at it. If someone has found a magic trick, please email me 🙂

Test Feeding

The proof is in the pudding right? I had to test in my shop vs. the range so that meant I needed to be very careful about where the pistol was pointed. Do what you are comfortable with and be safe.

I loaded up three magazines with three rounds of each to start. All hand cycled just fine. Prior to the above tuning, I could not do that. I then loaded up full mags of each and repeated the tests – everything hand cycled just fine.

Conclusion

I hope to get to the range at some point this week to verify the results. I fully expect it is good to go now. Also, let me again use this opportunity to point out this is why you always need to test your combinations of pistols, magazines and ammo. The TRP Operator is an excellent pistol but I knew not to rely on it out of the box. There are just way too many variables to take that gamble.

2/16/2021 Update: Read this post where I list the Q&A between readers and myself about the TRP.

Save on End Mills and Other Cutting Tools – Two Solid Vendors I’m Using

Everyone is trying to save money these days and that includes me. When you start talking about quality carbide end mills and cobalt drills, the costs rack up fast but there are options for you to save money and I’ll make this short and sweet.

To be clear, these folks did not pay me or even know I was going to do this blog post. I’m not getting a dime from them.

Drills and Cutters

I needed to buy a 3/4″ reduced shank cobalt drill bit. These things are usually around $40-50/ea and I was able to get a nicely made Qualtech from Drills and Cutters for $32.91 out the door. I use this bit for drilling out the top of my AK-12 grips and the glass reinforced polymer shreds HSS bits so discount Silver & Deming bits don’t last. Spending the money for a quality bit made from cobalt makes a ton of sense because it will do hundreds of holes before it needs to be sharpened.

So, Drills and Cutters is a web store that you can buy from and they may have the manufacturer ship direct to you. I have found their pricing and shipping speeds very good.

They sell drill bits, taps & dies, cutters & saws, reamers, end mills, carbide burrs, annual cutters and more.

So, if you want to save money, check them out at:

https://drillsandcutters.com/ or call them at 1-800-870-3201


End Mill Discount

The second group I want to share with you is EndMillDiscount.com. Carbide is not cheap and “cheap” carbide tooling does not hold up. I go through a fair number of carbide end mills and carbide spotting/centering drills each year. When you need to drill hardened steel, there are situations where you simply need the hardness to cut. So, I needed to order in more 1/4″ bits and started shopping around. With the word “Discount” in the site’s name I was a little nervous but they had *really* good prices and I couldn’t find any negative reviews so I took the plunge.

I ordered 4 of the HTC 4-flute 1/4″ diameter end mills at $7.15/ea and 2 of the SwiftCarb Spotting/Centering drills at $16.98/ea and shipping was only $10.51. Wow, in just a few days the end mills arrived drop shipped from HTC and then the drills arrived drop shipped from SwiftCarb. I was very impressed.

Do you ever look at a photo and ask yourself “Why?” I don’t know why that big end mill is in the photo at the bottom. The smaller 1/4″ bits are what I ordered from End Mill Discount. They worked great by the way.

End Mill Discount sells end mills, drills, micro tools, cutters, cobalt tools, carbide burrs and more.

I definitely plan on buying from them again. Visit them at:

http://www.endmilldiscount.com or call them at 1-888-305-TOOL


I hope this helps you out.

Great Deals On Pistol Braces and Pistols With Braces At PSA

When the ATF reversed the ruling about braces and enabled folks to use them however they saw fit, the demand and supply of pistol braces went into orbit. I have carpal tunnel and a hereditary tremor so for me, using a brace is the only way I can wield a heavy pistol – such as one based on an AR, AK or MP5 type of action.

Examples of Braced Pistols

SB Tactical’s PDW brace is great on AR pistols
IWI Galil Ace in 7.62×51 with a SB Tactical SBA4 adjustable brace
PTR PDWR .308 pistol with a SB Tactical folding mechanism and SB Tactical SOB brace

Palmetto State Armory (PSA)

PSA has come a long way. I’ve used them as my go-to AR parts supplier for years and now they have great deals on parts, kits, receivers, and firearms. They also offer some great deals on braces – by themselves as parts, as part of a kit offering or even on firearms.

Brownells Has All Kinds of Metal Finishes And Surface Preparation Supplies

Folks, if you are looking for supplies to finish your firearm, Brownells is a great source. I’ve done business with them for years and they have provided me great technical support as well as customer service. If you are considering a spray on finish like Alumahyde (their own product), Cerakote, Duracoat, or Gunkote plus other finishes like cold bluing, hot bluing, color case hardening or parkerizingBrownells has a ton of options for you.

Both of these rifles were finished using Duracoat’s spray on finish. You really needed to blast the surface, make sure it was very clean and then allow the finish to cure for a week for it to be durable.
Baking on Molyresin over manganese park. That’s a M92 with a long barrel in the front and a M72B1 in the rear from back in the days when I had free time 🙂

These days, I do a base surface preparation of manganese parkerization and then Norell’s Molyresin on top. The park creates an ideal surface for any sprayed on finish like Alumahyde, GunKote or Molyresin to stick.

The following are some great examples of products they carry:

How to Make An Affordable and Effective Heated Tank For Acid Etching – Part 2

In the last post, I covered the basic construction of the tank. In this post I want to talk about heating the tank. Thanks to mass production of digital temperature switches, you can build a digitally controlled heated tank for a very reasonable price.

Why Does Heat Matter?

In case you are wondering, heating the solution does matter. Years ago, in 1889, a chemist by the name of Svante Arrhenius proposed an equation that would later bear his name. Basically, a chemical reaction increases as the level of activation energy increases. The reason temperature enters in as that you are raising the energy in the liquid, more energetic particles are bouncing around and increasing the volume of reactions which means that more successful reactions will occur as well. We can use a rule of thumb that for each 10C increase in temperature, the reaction rate will double and for each 10C drop, it will be cut in half. To sum it up, cold=bad for chemical reactions. As a side note, this is also why marginal batteries fail when cold weather hits.

So what this means to acid etching is that in my cold unheated shop in the Winter, reactions are going to be real, real slow. Thus, I must have a way to heat the chemical and the submerged part to improve the reaction.

The Heating Element For The Tank

The first thing I wanted to do was to keep the cost down and the second was that I didn’t want something that would get so hot that it would melt the PVC. I had a 30 foot length of roof heating tape from when we cleaned out my dad’s garage that I had been thinking about for a while. It always makes me feel good when I use something that was my dad’s. (There are tons of options on Amazon – click here.)

These roof heating cables use AC voltage to warm up and melt ice are readily availble and are designed not to get so hot that they melt the shingles but also are designed to be spread out and not right next to each other so I was going to need to test the design. I planned to wrap the tape from the bottom of the tank until I ran out cable with each coil right against the previous. I was counting on convection of move warmer fluid up and cooler fluid down but I wasn’t really sure how it would sort out.

Another nice things about these heating cables, or heating tapes, is that they do not use a lot of electricity. The 30 foot model my dad had was spec’d to draw only 150 watts at 12 volts. That makes for a nice portable unit that you can run off just about any extension cord.

So, step one, I applied the tape to the empty tank and secured it just with 3M 3340 aluminum HVAC tape. This is the tape made for higher temperatures with an aluminum foil backing – it’s not dcut tape. I then watched the temperature with my Fluke 62 Max IR thermometer. You need an accurate thermometer and the Fluke has served me very well – it’s proved itself to be accurate, reliable and durable – it’s been bounched around a lot in my shop.

So, the temperature slowly climbed but made it all the way up to 170F before I shut it down. The PVC still felt pretty good but it was way hotter than what I wanted. Just plugging the tape in and calling it done was not the answer. Sure it would heat the liquid up fast but I couldn’t safey leave it unattended. I needed something to control the temperature but use the heat tape.

Please note that there are pipe heaters that are a different creature. Some of them need to be submerged in water or wrapped around a steel pipe. Do not use those types of heaters. There are a ton of different names buy you are looking for the cable or tape that is put on roofs to melt ice dams, etc.

Solution – Use A Digital Temperature Controller

I thought I knew the switch I was going to buy until I did some further research. Some controllers are very easy to set up and others seem a bit more confusing. I opted for the WILLHI WH1436A Temperature Controller 110V Digital Thermostat Switch. All you do set set the temperature for ON and the temperature for OFF. That’s it. If you want them, there are some more advanced settings that you can explore if you want but this seemed like just what I needed.

I undid the top few coils of the heat tape and rewound them with the temperature probe wrapped in them. I then used aluminum HVAC tape to secure the top. I set ON to 90F and Off at 95F and plugged the roofing tape into the controller.

I inserted the temperature probe a few coils down and secured the top with 3M Aluminum HVACtape. Note the small cable clamp screwed into the wood base securing the bottom of the heater tape and preventing it from unwinding.

I started watching with the Fluke meter and since the temperature based on the probe was 40.2F, the controller turned on power to the switch and the tape heated. It did cut power around 95F but the tape continued to warm up even so by about 10F so the peak temperature was between 103-105F according to the Fluke. This was actually within my acceptable range. I was just ballparking 90F but even 105F was fine by me.

The digital controller works well. I’m going to leave it loose some I can move it around depending on what I am working on and were.

There was one minor hitch I noticed during experiments – the controlled heat took over an hour to warm up the fluid. If I unplugged the tape from the controller and plugged the tape straight into AC power, the fluid heated way faster and the pipe never felt soft – probably because the tape was heating part of it and the acid was cooling it. This was the fastest way but risky because if you forget, it’s going to get quite hot. I let the fluid get up to 160F during one run and decided that I would only do this if I was in a big rush and going to be there working the whole time. If I wanted to play it safe, letting the controller keep things safe was a better bet. I could have also sped things up by setting the OFF temperature higher, say at 110F and that’s something I will experiment more with.

The temperature controlled tank worked out great on these high carbon steel damascus blades.

Operating Temperature Range

Do not heat ferric chloride past 131F. Remember that the heating element will still heat the chemical another 10 degrees or so past the upper limit you set as OFF.

The operating temperature range from MG Chemical is 95-131F. Based on my results, I don’t see a need to push the upper limit.

Click here both for their technical sheet and MSDS sheet,

Conclusion

I had about $30 in the PVC and fresh glue, nothing for the base, the controller was $29.99 and the roof heat tape was free but if you bought it, the price would be around $30. This definitely falls in the affordable category plus I turned out some really cool etched damasus blades using the controlled tank. If you want to know a bit more about the chemicals and my process, click here.

When I was done, I let the tank cool down, screwed on the lid, cleaned things up, coiled the cords up and stored the tank for the next use.

PSA AK-V Part Three: Changing the Brace, Adding a Red Dot and Installing A Quick Takedown Pin For The Dust Cover

Out of the box, the AK-V is impressive. The trigger is decent, the grip and handguard are functional but there were three things I really wanted to do – move to a SBA4 brace, install an optic and create a quick takedown pin so the dust cover could be removed (the big reason I bought the AK-V from a business perspective). So let’s step through each.

Palmetto State Armory (PSA) has a stunning array of Kalashnikov firearms now. AK-47s, AK74s, 100 series, rifles, pistols … it’s impressive. Click here to go to their main AK menu.

Replace The SBA3 Brace With An SBA4

Yes, they are both adjustable braces but that comparison ends there. The SBA4 is much more sturdy and has five length of pull adjustment positions. The SBA4 does go on sale and that is the time to buy one. I got mine for $99 at PSA’s July 4th sale and there was free shipping!

The SBA4 is the top brace and the SBA3 is the bottom. You can instantly see the SBA4 has more bracing and is bulkier. The back end does not flop around either unlike the SBA3.

Now PSA did something with the SBA3 that is a best practice. They staked the castle nut to the receiver end plate. Now, I started thinking about what would be my easiest option and it dawned on me that if I was SB Tactical and wanted to control cost and complexity, I would try and have as few inventory parts as possible and that means as few buffer tubes. Guess what? The SBA3 and the SBA4 both use a Mil-Spec 6 position buffer tube. Problem solved. You can remove the brace just like most AR/M4 stocks – lift up on the locking pin and slide it right off.

The Castle Nut has two real solid stakes in it. Kudos to PSA.
Ta-da! Under the brace is a Mil-Spec buffer tube or “receiver extension” depending on who you talk to. The SBA3 and SBA4 use the same tube!! Note, the weapon is upside down for this photo.
Here’s a good shot of the receiver. See that small vertical slider switch just above the mag catch? That’s the bolt release. The M4 buffer tube / receiver extension they are using is rock solid. If it is made by someone else, I don’t recognize it.
Here’s the tail end of the SBA4 on the left vs. the SBA3 on the right.
The SBA4 uses the same buffer tube and slides right on in place of the SBA3 brace.

The result is a very sturdy brace. After comparing the two, I will only use SBA4 braces going forward.

Vortex Crossfire Red Dot Optic and American Defense Mount

I doubt I will ever go past 100 yards with the AK-V and a much more likely engagement distance is 50 yards so a red dot is perfect. I’m a huge Vortex Optics fan and this was a perfect situation for their Crossfire Red Dot mounted on an American Defense AD-T1-L STD quick detach mount. They are my favorite combination of price and performance these days.

By the way, be sure to keep a couple of spare 2032 Lithium batteries in your case or range bag. Nothing dampens a range trip like dead batteries. It’s also why I use a quick detach mount – if the batteries are dead or that optic fails, I am yanking that optic off.

With the AD-T1-L STD mount you are a tad higher than the AK-V’s sights. I plan to watch how they relate at the range so I can ballpark where to aim if the battery is dead and am in a rush. Practice, practice, practice and not just when everything works.

Here’s the Vortex Crossfire Red Dot on the American Defense AD-T1-L STD mount. If you wonder why I use American Defense, it’s for the quality. Cheap Chinese/import quick detach rings shoot loose, don’t return to zero and bend/break over time. AD stuff is rock solid made from aerospace aluminum. Note, you can see our Quick Takedown Pin just above the handguard and I’ll cover that next.

The AK-V Dust Cover Quick Takedown Pin

I had to look up — I built my first Yugo M92 in 2012 and instantly hated the hinged dust cover. I drilled out the rivet and came up with a stainless pin with a ball detent and pull ring to secure the cover. The rest is history. I wound up making pins for the M92/M85, Tula and Bulgy Krinks use the same pin, Vepr shotguns and now the AK-V.

The reason for wanting a quick takedown pin is plain and simple, when you want to clean the weapon or work in the receiver, the hinged dust cover is in the way. To remedy this, you can install our AK-V quick pin and it’s about a 10 minute job if you know how to strip down an AK. This is a quick overview:

  1. Ensure the weapon is empty.
  2. Field strip the weapon like you would any AK, remove the gas tube and the lower handguard so they are out of the way. 
  3. The AK-V’s hinge is simply a 5/32″ roll pin that needs to be tapped/punched out so use something like a bench block to support the weapon and create a hole/gap for the pin to exit into.
  4. Use a 5/32″ roll pin punch and a hammer to tap the roll pin out.  You can save it for the future in case you ever want to use it again for some reason. 
  5. Put the dust cover back in place with the hinge holes lined up and slide in our quick takedown pin.
  6. Re-assemble the weapon.
  7. Done
Here, I have the rear sight block fully supported by the bench block behind it and am using a 5/32″ roll pin punch and hammer to drive the roll pin out.
What makes a roll pin punch different from a normal punch is the dome in the middle that centers the punch on the pin and makes driving the pin out very easy. It also reduces the risk of a regular punch slipping off what you are working on an scratching the finish.
So this is what you wind up with once the roll pin is removed.
This was my first attempt because I am right handed. Having the pull ring there right next to the gas tube locking lever was just too much. I flipped it around and had the pull ring on the other side of the gas block.
This is how I am running it now. The pull ring is on the left / non-operating side and the ring is tucked just behind the handguard.

We have the pins up for sale on our website now. Click here to order one.

Summary

Looking good!

The AK-V was almost done at this point. I still needed to lubricate the weapon and put it in a suitable case. I’ll tell you about that part of the journey in the next post.


This is a four part series on the PSA AK-V 9mm:


Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Upgrading To Truglo TFX Pro Sights On Your Glock Compatible Pistols Including Polymer80s

The factory sights on Glocks leave a lot to be desired in my opinion. I like fiber optic sights but also want sights that generate their own light at night. Fortunitely, TruGlo has upgrade sights for Glocks that can do just that. They are the TFX Pro model sights.

The fiber optics use daylight and are very nicely visible. I know there is a trend for red dot optics on pistols but I would rather opt for simplicity. The other really nice thing about these sights is that they use tritium to generate their own light at night – some sights make you charge them with a flashlight but not these. The only issue to bear in mind is that the Tritium isotopes with flouresce for about 10 years and then be dead. My thinking is that is a loooonnnngggg time from now plus it just would affect the night use at that time.

So, let’s get to it, Installation has two discrete steps – replacing the back sight and then the front sight. Both of these can be done by most home gunsmiths because the Glock design is pretty forgiving. Some pistols require a top notch MGW sight pusher to be removed but not the Glocks. The below is based on my experience installing these sights both on my Polymer 80 based Glock 17 and 34 Gen 3 compatible pistols.

Tools & Supplies

I’m kind of like Tim The Toolman Taylor, if you remember the show Home Improvement. I like tools and don”t need much an excuse to buy one in order to try and do the job the right way. When it comes to the rear sight, some guys use a 3/9″ piece of Delrin or wood dowel to tap the old sight out. Because of my hand tremor, that’s risky for me so I looked into sight pushers and decided to go with the Wheeler Engineering Armorer’s Handgun Sight Tool.

For the front sight, a dedicated Glock front sight tool can make the job a ton easier because they are shallow and have a magnet that will hold the tiny screw in position while you get it started. A regular nut driver is too deep and the tiny screw will fall into it vs. being held nicely in position.

You will need some medium Loc-Tite to secure the front sight screw.

Tape to wrap the slide and protect it is a recommended. I use painter’s tape.

Getting Started

  1. Make sure the weapon is unloaded and clear – no magazine and nothing in the chamber.
  2. Remove the slide
  3. Remove the spring and the barrel to get them out of the way – you don’t need to remove anything else.
  4. Wrap slide with painters tape to protect it from scratches leaving the two sights exposed.
  5. I did my back sight first and then my front sight.

Procedure – Back Sight

  1. To remove the back sight. I followed the instructions with the Wheeler unit and flipped the pusher over to use the angled face. Mine was set for straight-edged sights from the factory.
  2. I also oiled all of the threads on the Wheeler.
  3. I secured the slide in the Wheeler unit taking care to make sure the slide was the right height so the pusher would engage the sight and not bind on the slide.
  4. The factory Glock rear sight pushed out incredibly easily. I can see why some guys just drive them out. However, I really liked the control the Wheeler gave me.
  5. I then lined up the replacement sight and pushed it into place – checking over and over and making minor adjustments to ensure it was in the center.
  6. The Truglo has secured by a set screw that I backed out, put a dab of blue/medium Loc-Tite on and then tightened down.
  7. That was it for the back now on to the front.

Procedure – Front Sight

  1. Turn the slide upside down and you will see a small hex head screw that must be removed. I used my Glock Front Sight tool for that.
  2. Push or tap out the original sight.
  3. The replacement TruGlo unit is a tight fit I had to firmly press it into position. It is an interference fit so don’t remove a ton of material so it just falls into the slot cut in the slide. It needs to be pressed in as this helps with alignment and retention.
  4. Put blue/medium Loc-Tite on the screw before reassembly. This is mandatory. If you do not, it will shoot loose over time and you will lose your front sight.
  5. Use the Front Sight tool to reinstall the screw with the Loc-tite and tighten it down.
  6. Done.

Conclusion

I really like the TruGlo TFX Pro sights. They are very visible both during the day due to the fiber optics and at night due to the Tritium. They were well worth the investment. I hope this helps you out.
