  • Proprietary coating for easy maintenance and long life
  • Vents gasses away from line of sight at dual 45° angles for clean sight picture


TANDEMKROSS is widely known for their successful line of compensators. Now joining the ranks of the Game Changer, Game Changer PRO, and Game Changer PRO Squared is the Game Changer PRO Squared for 9mm! Threaded for standard 1/2"x28 threaded barrels, this compensator will fit a WIDE variety of 9mm firearms!


Made of steel, this compensator is impervious to gas cutting and adds a welcome amount of weight to the muzzle for balance and recoil mitigation. The durable steel and proprietary coating also help to increase this muzzle device’s lifespan. Not only does the finish make the compensator look amazing, but it aids in the maintenance and cleaning by making it more difficult for lead and carbon to accumulate on the surface.


Beyond just the weight, the 9mm Game Changer PRO Squared Compensator also ports the gasses upward to actively fight against muzzle rise and help keep you on target. While many compensators function on a similar principle, TANDEMKROSS’s unique design does this while intentionally keeping your line of sight clear and porting the gasses away from you. Dual 45° ports on either side of the bore axis guarantee smoke and gas are directed out and away to preserve your sight picture.


All TANDEMKROSS compensators are shipped with a rubberized O-ring to ensure proper timing and a secure fit without any need for thread lockers or permanent modifications. 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. Grab an assorted Washer Kit for TANDEMKROSS Compensators here to complete your build.


Rather for competitions like Steel Challenge or target practice, TANDEMKROSS’s Game Changer PRO Squared Compensator for 9mm firearms is a must-have solution for anyone looking to improve the performance of their favorite 9mm firearm.

    Works great on 9mm carbines but if using on a pistol I would recommend getting a recoil spring suitable for a suppressor. Works fine but cycling on a stock recoil spring makes some models a bit sluggish during cycling.
