In terms of felt recoil standard systems ramp up resistance as the slide begins its rearward motion then decrease resistance as the slide catches on the frame - causing muzzle flip. However the Nighthawk Custom 1911 Everlast Recoil System maintains a steady consistent resistance throughout the recoil cycle greatly reducing muzzle flip. You can also trim the length of the guide rod if needed. Install the Nighthawk Custom 1911 Everlast Recoil System on your 1911 for incredible gun handling that won't leave you feeling short changed.
