Great Compensator!! by chip0105, Verified Owner, April 30, 2024
Though this compensator might feel a little bulky on the front of your Glock, in my honest opinion, it considerably reduces muzzle flip. I now have 4 of these and I would highly recommend them to anyone looking to increase their accuracy; especially...

simple yet effective by Teddy Rivera, Verified Owner, November 9, 2024
If you are on the fence about compensating your Glock 19 well I can tell you this is well worth it. More muzzle control for fast follow up shots makes this product a keeper. Yes it does add length to your slide but that part of the gun should be bel...

Product Info for Strike Industries Mass Driver Barrel Compensator

For the smoothest draws, use a compensator such as the Strike Industries Mass Driver Barrel Compensator to counter recoil. These PSR accessories from Strike Industries are designed to be used with Glock handguns without permanent modification, and the innovative design is the foundation of the Mass Driver concept. When you draw your Glock, the compensator moves to absorb the recoil, which reduces your felt recoil. If you close your eyes and hold your gun normally, you might just notice the comp moving slightly forward. Widen the bore, if you wish, but the compensator won't affect your shooting in anyway. The integrated 2.5mm relief cut and the forward-facing port diminish the lip that typical compensators create, reducing lipping and damage to the face of the slide. A blend with the shape and texture of your handgun gives this device a no-snag, smooth draw. Use the Strike Industries Mass Driver Compensator with your Glock handgun for a recoil-reducing upgrade that is sure to impress your shooting partners.image
