It was a couple of months ago I received the Uni-Comp by Tyrant Designs for review. The Uni-Comp is a 5/8″x24 thread universal compensate for 9mm pistols with a 5/8″x24 threaded barrel. It is a two-piece design that attaches to the threaded barrel without modifying your pistol. In the box comes the two-piece Uni-Comp, wrench to tighten it, a bag with three O rings, and some hearing protection.
The two pieces are the stem and body. The first step, after ensuring the pistol you will be attaching the Uni-Comp to is unloaded and clear, is to install one of the included O rings on the groove at the end of the stem. You have two extras in the event one breaks, but there were no problems with the 500 and some off rounds we ran through the comp. Once the O ring is installed, the body is threaded onto the barrel, first getting it threaded on far enough for the stem to thread but not so far as to bottom out on the slide. This is illustrated much better in my video portion of this review at the end of this article.
Once you have the body positioned, you then thread the stem into the body onto the threaded barrel as well. Once you get it hand tight snug with the included wrench. You do not have to time the ports on the stem, so once you get it snug, you are good to go. You want to be sure the stem is plenty snug at this point.
Once you have that all together, you are ready for the drag strip, so to speak. We ran the Uni-Comp on the CZ SP-01 Tactical, as reviewed here with the Cajun Gun Works and Alumagrips upgrades, as reviewed here. My Gen 4 Glock 17 with threaded Lone Wolf barrel was also used as a host as we swapped the comp back and forth. You can find the Lone Wolf barrel review here. The Uni-Comp has a few options of the stem color; you can go with silver. black, or gold with silver being my choice.
Compensators indeed do help with mitigating muzzle flip and perceived recoil, and the Un-Comp did it’s job well and without issue. By directing some of the gas up instead of straight out, you get a downward pushing effect at the muzzle, working against that muzzle flip. This helps a great deal in pistol matches where tenths of seconds count quickening follow up shots and target transitions. With the Uni-Comp being slim and unobtrusive, it would be feasible to run it in a carry gun if you saw fit, transferring those benefits from your race gun to your carry gun. While only adding a few ounces to the muzzle and a bit of length, it did not hamper reliability with either the CZ or Glock. You would want to be sure your carry holster would accommodate the compensator. Understand the Uni-Comp is not designed to work on fixed barrel rimfire firearms. The Uni-Comp is made in The United States and carries a lifetime warranty, at about eight dollars and the ability to easily swap from pistol to pistol it is certainly worth a try.
