Description
The genuine SIG SAUER OEM factory spring is a critical ignition component engineered to maintain your pistol’s textbook operational reliability and drop safety. For classic hammer-fired P-series pistols, this spring provides the necessary tension to return the firing pin to its rest position after every strike, preventing primer drag or inertial discharges. For modern striker-fired platforms (P320/P365), this is the main driving spring that propels the striker forward with the required velocity to detonate the primer. Replacing a worn spring as part of routine maintenance is essential to avoid light primer strikes and failures to fire.
