Recoil Systems

RECOIL MASTERS & SPRINGS

The STI Recoil Master is designed to achieve softer recoil and bring the pistol back to point of aim quicker by using two springs for recoil verses the traditional single spring.

The 5.00″ Recoil Master will fit all government model 1911 style pistols. (Some fitting may be required for non-STI firearms.) The 4.15″ and 3.90″ are designed for STI pistols only.

Note: The primary spring on your STI Recoil Master should be changed out every 5000 rounds, and the Recoil Master itself replaced after 25,000 rounds. Failure to do so can result in damage to your pistol.
