The Magnum Research DE1911G10 10mm Pistol - I Really Like It!

Ok folks, I’m experimenting with 10mms again. I had a run in with a bear last summer and while nothing happened, it sure made me want to carry a more powerful pistol than a 9mm. Years back, I had a Dan Wesson Bruin and a Rock Island 6″ Ultra that were both in 10mm that I eventually sold and was firmly in the 9mm camp for years.

My first 10mm to try out this time around was a Springfield Armory TRP Operator with a 6″ barrel. Folks, I genuinely was not impressed and reliability sucked out of the box (click here for a blog post about that). So I dug around and ran into the Magnum Research 1911-style pistols. Know what? They get great reviews and guys kept mentioning how well they were made and what great triggers they had.

I ordered a DE1911G10 pistol and it arrived a bit over a week later so I rushed over to my friend Scott Igert’s gun store (Michigan Gun Exchange) and checked it out. I was genuinely impressed by how smoothly the action cycle and the excellent trigger right out of the box. I’m used to things being gritty or really tight from lack of lubrication but this pistol was remarkably smooth. I’ve only encountered one other pistol this way – my Dan Wesson Bruin was slick – but nothing has come with this nice of a trigger right out of the box.

Before going further, let’s take a step back and look at who makes this pistol.

Magnum Research Makes 1911 Pistols?

The short answer is “no” but they do sell them. I owned a Desert Eagle Mk.V .44 magnum way back in the 90s so I was familiar with the Magnum Research (MR) of old but kind of stopped keeping track as the years went by. I did some digging and over the years they worked out deals with other firms to make certain pistols (for example IMI/IWI and Saco) they sold and eventually MR was bought by Kahr Arms in 2010.

The firm that actually makes the MR 1911 pistols is BUL Armory of Tel Aviv, Israel. They were founded in 1990 and make a wide range of CZ, 1911 and 2011-style pistols. Their pistols have s great reputation and are in use all over the world.

My Pistol

It’s a good looking pistol and I am glad it doesn’t have the huge gaudy engraved letters on the side that previous Desert Eagle 1911s had. If you don’t know what I mean, just look at some pre-2020 articles or posts and you’ll see.

I had to wait for some time to take the pistol apart, clean and lube it before going to the range. For those folks new to firearms reading this – you always clean and lubricate a new firearm – even if they come in a bag soaked in oil.

The DE1911G10 disassembles like any 1911 with one big exception – does not have a bushing so to remove the slide assembly requires the insertion of a pin in a hole they machined in the recoil spring guide (the round metal rod that the recoil spring rides around).

It seems like I am seeing fewer pistols with bushings – at least 10mms. The ones with a setup like this make takedown very easy – you lock the slide open, put a bent pin (MR/BUL provides one) into the exposed hole in the recoil spring guide, release the slide and then the recoil spring tension is removed. Everything then strips down real easy – easier than even traditional 1911s in my opinion because you aren’t fighting any spring tension trying to shove the slide forward.

With the pin in place and the slide released, the pin holds the spring in place. Note, I released the slide by gently racking it – not just dropping the slide stop as that will slam the recoil spring parts against the pin unnecessarily. If you don’t have a factory pin, you can bend a small paper clip to have a small 90 degree leg on one end. It doesn’t look very good but it does the job.

You pull the spring assembly straight back and out – including the pin. Just take care not knock the pin out. A 10mm pistol uses a stout spring and it will be a bear to re-assemble. A valve spring compressor is a huge help – click here for a post about it.

Cleaning and Lubricating

For a while now, I’ve been using RamRodz to clean pistol barrels and bought packages for both my 9mm and 10mm pistols. I like how tight they fit and I can really clean out the barrels. I coat them with CLP to do the cleaning, lubrication & protection (hence the acronym CLP).

I wiped everything down to remove any dirt or debris from the factory. Other than the oil that coated the pistol from the factory it was very clean. In looking at the parts, everything was nicely made, fitted and assembled. So far, so good.

Here’s the field stripped pistol with all of the major parts plus you can see the RamRodz, CLP and my precision SuperLube applicators.

To lubricate the pistol, I use Superlube liquid to get all of the traditional points except for the slide rails and the heavy bull barrel. On those I user SuperLube synthetic grease to make things slick. Folks, when it comes to lubrication you will get a million opinions and get into arguments. It just so happens that I find SuperLube works really well and I use the grease on all of my firearms now where parts slide together. It’s a synthetic grease and it has tiny PTFE (Teflon) particles in it to help with lubrication. I know when you hear “Super” in anything it sounds like a rip off but this stuff really works and I have been using it for a few years now on my pistols and rifles.

I use an acid brush to lightly apply SuperLube grease to all surfaces the slide – the frame rails and the bull barrel because it directly contacts the slide. It makes one heck of a difference folks.

Re-Assembly

Again, it’s just like a 1911 with the exception of that recoil spring assembly. Just insert the barrel into the spring and then carefully insert the recoil spring assembly so the groove is against the barrel and don’t knock the pin out of the hole.

Video For People New to 1911 Pistols

If you are new to 1911s I have great news – there are tons and tons videos, blogs and books about how to clean and care for your 1911. Just remember by comments above about there not being a bushing and the takedown pin you insert in the recoil spring guide — otherwise it is the same.

The following video from Ruger has a very similar bull barrel, no bushing and uses a pin. The person doing the video does a nice job.

This next video covers re-assembly:

These next two videos provide nice overviews of cleaning a 1911:

Conclusion

The action and trigger were so slick at this point! I was deeply impressed. After lubricating, the trigger pull averaged about 4 lbs 2oz using my Lyman digital trigger pull gauge. In general, I like the trigger – I can feel where it is going to break and then can cleanly pull through.

Okay, with this part done and my seriously liking the pistol up to this point, I had to take it the range and that will be the next post.

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.
