Keep your SIG P320 full-size pistol running like new with this complete parts kit, engineered to support .40 S&W, .357 SIG, and .45 ACP configurations. Designed for armourers, gunsmiths, law‑enforcement armories, and responsible owners, the kit gathers the commonly replaced small components needed for routine service, rebuilds, or armorer-level maintenance.

Typical kit contents (may vary by SKU) include: firing pin and plunger springs, sear/striker springs, trigger and connector pins, detents and plungers, extractor and extractor spring(s), ejector, magazine catch and spring, slide stop, disconnector parts, safety/selector springs, and other wear items manufactured to OEM‑style tolerances from heat‑treated materials. Components are finished to resist corrosion and wear and are selected to match the dimensional and functional requirements across the listed calibers.

This kit does not include serialized major components (frame, slide, barrel). Ideal for reducing downtime during repairs, simplifying rebuilds, and stocking armourer benches. Always follow manufacturer procedures and perform a full function and safety check after installing replacement parts.
