When shooting in a competition, even milliseconds can mean the difference between first place and second place. The Game Changer PRO 9mm Compensator is the perfect addition to your Ruger® PC Carbine™ or other 9mm competition firearms to significantly reduce muzzle rise and boost your speed and accuracy.

Like our original physicist-designed Game Changer and Game Changer PRO .22lr compensators, the Game Changer PRO 9mm adds weight to the front of the pistol for better balance, reducing muzzle rise and improving accuracy when moving quickly between targets. The compensator vents gases at dual 45° angles for better visibility and control.

Love shooting with a compensator but hate the cleanup? The black Game Changer PRO 9mm features a proprietary Easy-Clean Coating to make compensator maintenance simple. The Game Changer PRO 9mm compensator is easy to install and fits any standard 1/2 x 28 threaded barrels.

Due to varying tolerances and use cases, some have found it helpful to also use any number or combination of washers with their O-ring for the perfect custom fit.

Works as Advertised
I've put about 800 rounds down range with this compensator in place on my Ruger PC Carbine and it works as advertised. 1. It provides marginally quicker target acquisition. 2. The carbine recoil does not move left or right. 3. The carbine recoil does in fact push straight back and the slight additional thrust can be felt.

Nice Addition
I have had a Ruger PCC 9 for about a year. It’s been a great riffle to shoot. This compensator was easy to install and made for smooth transitions from target to target.

It works
Installed on a Ruger PC carbine and it simply works. IMO the 45deg angles work well and do not obstruct the sight picture like full flat breaks do.

Looks great & works great
This compensator looks & works great. It took out what little muzzle rose that the PC Carbine has.
