The STI Recoilmaster is designed to achieve softer recoil and bring the pistol back to point of aim quicker. Using two springs for recoil verses the traditional single spring, provides at least 10 times the life of a conventional recoil system. The 5" RecoilMaster is available in a light or heavy system, to accommodate most 1911 load applications.

The 5.0" RecoilMaster will fit most 5" government style 1911's.
