High quality 304 stainless steel bushing replaces the factoryo Ruger bushing, allowing for safe removal of the magazine disconnect from Ruger® MKIII™ and 22/45™ pistols. Removing the disconnect allows the magazine to fall free from the gun, proper seating and allows the gun to fire with the magazine removed. Another added benefit is simplified takedown and cleaning. Once installed, the bushing will not effect trigger function or feel.
