My Glock 22 in Machine Pistol Configuration

I was generally satisfied with the Glock 23 Machine Pistol configuration that I assembled, it can easily contain short full automatic bursts into a man-sized target at around 13 meters. However, I felt I could build a better Machine Pistol, one that would enable me to shoot full automatic bursts accurately at even longer ranges. For this reason, I decided to buy a Glock 22, as I felt the recoil-reducing accessories and/or parts necessary for building a better Glock Machine Pistol are only currently available on the full-sized Glocks. 

These recoil-reducing accessories are mainly the Endotactical Tactical Stock Adaptor - Glock (TSA-G), coupled with a Magpul Utility Battle Rifle (UBR) Stock. I have reviewed these separately, you can find them here and here. Aside from this, I also used the CAA Tactical Folding Grip Glock - Small (FGG-S), and a Lone Wolf Compensator (coupled to a Lone Wolf Threaded Barrel).


'First Firing Range Session'
With everything more or less ready, I took my Glock 22 in its Machine Pistol configuration into the shooting range for the first time. I used Target Boards, at my standard range of 13 meters. First test was using the STOCK or FACTORY BARREL, with 50 rounds of Semi-Wadcutter, Teflon-Coated (SWC-TC) reloads in standard .40S&W loadings. Recoil was quite noticeable, with the UBR Stock jumping up and into my shoulders with some vigorousity. 

However, it was not enough to leave a mark, thanks perhaps to the UBR's generous butt stock surface area, and rubber pad. My group was very tight, a testament to the TSA-G's very solid and positive grip of the pistol. This grouping was much tighter than the similar semi-auto fire I used with the Glock 23 and its Fab Defense GLR440 Stock.


Next up was the same settings and rounds of ammunition, but this time in full-auto. I was able to keep all 50 rounds fired in full auto bursts at the target at 13 meters, but the group was quite large, covering the entire torso. The shots climbed straight up, from navel to neck, which is better than the diagonal climb to the right I found using the Glock 23/GLR 440 Stock in full auto. A straight climb up is a bit easier to compensate that the diagonal climb.

Last was the same settings in full-auto bursts, but using 50 rounds of prime Semi-Wadcutter Full Metal Jacket (SW-FMJ) bullets from Armscor, and with the LONE WOLF BARREL and COMPENSATOR. Surprisingly, the result was just about the same, not much improvement in the groupings of the shots.


'Shooting Summary'
I am quite disappointed with the full auto results. I thought I could build a better Glock Machine Pistol using the improved accessories that would enable me to shoot full-auto at longer ranges, but that did not happen. Despite the better stock configuration with the Endotactical Stock Adapter and UBR Stock, plus the Vertical Front Grip and even the Lone Wolf Compensator, I could barely keep my bursts on a man-sized target at 13 meters.

Overall, though, the full-auto accuracy is just about the same result I got with my Glock 23 Machine Pistol configuration, and such a result I feel are inferior to a true Sub Machine Gun (SMG) like, say, an Uzi or an MP5, based on what I have read. The only improvement in full-auto fire I noticed was the straight up climb instead of the diagonal climb to the right.

Then again, I did notice that the Lone Wolf Compensator spun out of place during the firing session. I tried to tightening it up again, but it kept spinning out of position after a few bursts. As a result, I don't think it was working effectively in terms of minimizing the muzzle climb, and thus I am invalidating this result and redoing it again, as soon as I find a way to keep that Compensator from spinning around during the firing process.

The new configuration shot very well in semi-auto. The groups are tighter than my Glock 23 Machine Pistol Configuration, and I feel I can easily hit targets quickly to 50 meters, and maybe even up to 75-100 meters with it in semi-auto.
