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.
