Glock with Trijicon RMR and One Source Tactical goodies.

You may be asking yourself, what can be done to a firearm to make it even better. While there are some items out there that are cosmetically nice, they don't really serve a purpose or increase the function of the firearm. I have found a thing or two that work great when put together. Of course, I'm not the only one that has done this.

I was at a class with an instructor that had something very interesting. We all had a firearm there for training purposes. There were six of us there, and most had different guns. The instructor had a Glock, but it was....awesome. I am sure that many of you have already seen videos on YouTube, or read reviews on many different websites, but this is the first time that I had seen one of these. It was a setup from One Source Tactical. They used to sell the whole gun, but now they just sell the slides, barrels and RMR (Ruggedized Miniature Reflex) sights.

This was back in January of 2012 when I first saw his pistol. I know some of you don't like Glocks, but this setup can be done to many different pistols. I know OST makes this same thing for M&P pistols for example. So I have been wanting one of these ever since I saw it. I would visit OST's site quite often and check out videos online.

Here is what the original gun was. Glock 19 with a match grade slide and match grade threaded barrel. On top sat suppressor iron sights, and a Trijicon RM07 RMR. I have links at the bottom for One Source Tactical, and the Trijicon RMR. You can get the RMR, slide and barrel from OST, but they were out of the RM07 when I ordered, so I snagged one from Amazon.

I'll paste a few pictures that I have on the computer. They are from a stretched out period of time from when I received all the parts and started putting it together, up until a couple days ago when I went to the range for a final sighting in.

First, the purchase of the pistol. I went to a local FFL and picked up a generation 3 Glock 19. I had to wait a little while for the slide and barrel to arrive so I went and put a couple hundred rounds through it before the goodies arrived.

Once all the goodies arrived I put them together and came up with this:

When I first tried out the new slide setup, the slide and barrel lockup were very sticky. I knew that having match grade parts would have pretty tight tolerances, but this was a little bit more than I was expecting. After shooting 700 rounds, it was still sticky in the lockup. After minimal shooting the groups would open up, even using a sandbag.

Also the red dot is supposed to co-witness with the iron sights, but it was off to the right when it was sighted in. I just need to move the rear sight a bit, but that won't be a problem.

I took the gun to a local gunsmith (Crusader Weaponry) and had him give it a look. He checked the barrel and slide fitting and realized that there was some extra metal that shouldn't be there. He filed off a little bit at a time and put it back together to check it. After some work it felt much better and wasn't difficult to rack the slide.

I took the gun back to the range on the same night and put another 100 rounds through it. I was able to get it sighted in nicely and it shoots much better. I used a bench rest to test it and set the target at 28 feet and had great results. The picture below is a five shot group.

The One Source Tactical/Trijicon RMR Glock is something that is really fun to shoot. It's very accurate and the RMR makes for fast target acquisition. If you have a chance to get one, I doubt you will regret it.
