HK SP5K Photo Shoot In The Leaves

Okay, I liked the leaves, the lighting and thought it would be a great chance to get some photos of the HK SP5K pistol with the SB Tactical SBTK5A brace and the Vortex Optics Crossfire red dot that is on an American Defense AD-T1-L STD quick release mount.  As you can see above, I’m still using the Uncle Mike’s case.

So those are a few from the batch.  Looking forward to taking it to the range some day.

PTR PDWR In The Leaves

The lighting was right, the leaves were on the ground and it was a great chance to get some new photos of my PTR 105 PDWR pistol.  This big pistol is the interesting brain child of PTR.  It’s essentially a cut down HK 91.

The PTR 105 configuration has a PTR metal handguard installed.  After messing with it some, I decided to install an MP5 handguard as I like the angle on the MP5 handguard more.  This also means I should have just bought the PTR 110 that comes with that handguard.

Now, the only problem is that the MP5 handguard is not as rigid as I would like.  I’ll experiment some with different handguards in the future.

The PTR 195 and 110 are big pistols at 23.5″ overall, 8.5″ barrels and weigh about 8 pounds.  I wanted to install a brace but needed to be mindful of Michigan’s odd 26″ maximum pistol length law.  This isn’t legal advice, but my understanding is that the Michigan State Police say that a pistol with a brace is measured from one end to the other in the minimum operable condition.  So, by installing a side folder, I could have a brace for when I wanted to use it but also had the minimum operable length at 23″.  What you see in the photo is an SB Tactical BTFA folding mechanism, buffer tube and SOB stock.  When open, the weapon measures 32.5″. 

Thanks to the BTFA folding mechanism, I can swing the SOB brace to the left and it locks open.  This keeps the brace out of the way of the ejection port.  You can configure the BTFA to go either left or right.
It definitely has clean lines.
The PDWR definitely likes the PPU battle packs of .308 FMJBT 145 grain ammo.  It works great and is plenty accurate within 100 yards.  I’ll need to try and shoot the PDWR for accuracy some day and see what it can do.

As you can see, the brace is folded open and operating side of the PDWR is nice and clear of any obstructions.

Given the PDWR is chambered in .308 and uses 20 round HK G3 magazines, that is a lot of firepower in a small package.  Overkill?  Sure.  Fun at the range?  Absolutely.

Basic SubGun Case for HK SP5K with Brace

As I wrapped up my changes on the SP5K, I realized I needed a case to put it in.  It just so happened that I had an Uncle Mike’s “Tactical Submachine Gun Case” that I had never used and it turns out the SP5K with the SB Tactical SB5KA brace and Vortex Crossfire red dot could slide right in without the magazine installed.

This is the front of the bag – six magazine pouches, one large flat pouch to the front and the rear mounted carry handle is visible.
This is the back – you can see the shoulder strap and the carry handle at the top.

The case has a zipper at the rear of the bag and the SP5K simply slides in.  This is one thing I dislike – it does not open and lie flat.  Some folks may find this a plus but I prefer bags that open.

The exterior dimensions are 24.5x14x2 and I’d knock off about half and inch all the way around for the interior dimensions.  It does have some padding but not a ton.

Another dislike I have is the way it holds the MP5 magazines.  They slide down in the little pouches and I can’t pull them out.  I need to push at the bottom to get them to slide up.

I pushed the magazines up so you can see them in this photo.  Notice where the bulges indicating the actual lower part of the magazine in each pouch.  In practice, the mags slide all the way down and are hard to get out.  You have to press from the bottom.

On the topic of pouches, the front pouch just forward of the magazines is very tight.  The bulge you see sticking out is a Mag Lula loader.  While it can hold the loader, it’s really better suited for thinner items.

Okay, rounding out my complaints, the carry handle at the rear makes for an odd front-loaded unbalanced load.  I don’t know why they didn’t center it.

Summary

It’s a decent entry bag for only $27.95 with Prime shipping on Amazon.  Sure there are things I don’t like about it but does the job.   I will be investigating other cases but this case is a solid performer at the price.
