Great, very compact compensator - Strike Industries Micro Threaded Comp - QUAD

Have used this comp on G19 & G43 Glocks and clones. Noticeably reduces felt recoil and muzzle flip. Works best with full-power rounds. Reduced-power rounds will not cycle properly when using this comp, unless a reduced-power recoil spring is installed. The comp is easily installed on any 1/2"-28 threaded barrel. ONE CAVEAT: Gas from the muzzle blast apparently can cause damage to the screw that secures / clamps down the comp on the barrel. I transferred the comp from one barrel to another after firing about 200 rounds. I noticed what appeared to be a nick in the threads of the machine screws, but didn't consider it a problem. When I installed the comp on another barrel, and attempted to tighten the screw to the specified 40 in/lbs of torque, the screw snapped in two, leaving the lower portion in the blind thread portion of the comp. Attempt to drill out the broken screw failed and comp was ruined. Purchased another to replace it.
