Sig Sauer parts kits and internals for the P365 platform (including the X-Macro variant) and the P320. Everything on the shelf here is a parts-only kit or grip-module aesthetic upgrade — no complete pistol, no complete slide.
What each kit does
Completion kits — the Sig Sauer OEM 9mm P365 slide completion kit (firing pin, extractor, striker assembly) and the Grey Ghost Precision P320 slide completion kit finish out a stripped Sig slide. Grey Ghost's P320 kit ships without a recoil rod, so re-use your OEM guide rod.
Lower parts kits — the 3CR Lower Parts Kit for the Sig Sauer P320 gives you a full fire-control refresh: trigger, sear, safety, springs and pins.
Grip modules and aesthetics — Tyrant Designs P365 X-Macro grip modules in Black, FDE and Gray; P365 X-Macro magwell in Black; slide caps in Black and Gold; +3 magazine extension; and the IntelliFire flat-face trigger in Black/Gold or Gold/Black.
Check your generation before ordering — the X-Macro is not the same footprint as a standard P365 or P365XL, and the P320 fire-control unit is the serialized part, not the grip module. Match up with a Sig P365 or P320 barrel, browse the broader Sig Sauer catalog, or add spare magazines. Free shipping on every order.
