P365 Striker Tuning Spring

This striker spring is designed for the SIG Sauer P365 platform and is a direct replacement for the factory striker spring.

+20% (Increased Power): 20% stronger than the factory striker spring. The added striker force gives a harder primer hit, which helps eliminate light primer strikes caused by hard-primer ammunition or aftermarket parts such as lightweight strikers. Trigger pull weight increase is minimal.

Reduced Power, -10% and -20%: lighter than the factory striker spring, for shooters tuning trigger feel for competition or range use.

IMPORTANT: Select your preferred spring power before adding to cart. Reduced power striker springs lower primer strike force and can cause light strikes with some ammunition. Function test with your carry or match ammunition after installation.
