The Ingenious Multi-Port 1911 Compensator Features a Built-In Barrel Bushing, Three Chambers and Seven Exhaust Ports for Maximum Recoil Suppression. Adding the Multi-Comp Compensator to your 1911 Auto is as fast and easy as changing out the barrel bushing and since the Multi-Comp can be used with your stock barrel, you have greater flexibility with your pistol at minimal cost.
