Sig Sauer P365 Recoil Spring Assembly 9mm Luger 3.1" Barrel Black

The Sig Sauer P365 Recoil Spring Assembly is a factory OEM replacement recoil assembly for the Sig Sauer P365 pistol chambered in 9mm Luger. The complete assembly pairs a solid guide rod with a matched dual recoil spring to deliver the same slide-cycling performance and reliability built into the pistol at the factory.

This assembly is specifically engineered for all P365 pistols with a 3.1" barrel. It is a direct drop-in replacement for worn or weakened springs, makes an excellent bench spare, and lets shooters refresh a service pistol back to factory specification. It installs with basic field-strip disassembly using common tools.

Sig Sauer designs the P365 family around distinct slide and recoil-spring packages, so correct fitment matters. This recoil spring assembly is not compatible with the P365 XL, P365-380, P365 XMACRO, or P365 AXG variants, each of which uses a different recoil-spring configuration. The assembly is finished in black and carries the Sig Sauer factory part number KIT365RECOILSPRING.

Whether you are performing routine maintenance after high round counts, completing a slide/upper swap, a gunsmith refreshing a customer's pistol, or simply keeping a spare on the bench, the Sig Sauer P365 9mm recoil spring assembly keeps your carry or backup pistol running at factory spec.
