SIG P320 SLIDE COMPLETION KIT

Description

The Sig Sauer P320 Slide Completion Kit is built for shooters who are assembling a P320 slide from scratch or replacing worn internal components and want factory-spec parts in a single package. Rather than sourcing individual small parts separately, this kit consolidates everything needed to make a bare P320 slide functional — with the exception of the barrel, sights, and recoil assembly, which are intentionally excluded so you can match those to your specific build.

The kit includes the extractor, extractor pin, extractor spring, extractor spring pin, a striker group assembly, and a rear slide cap. Each of these components carries a corrosion-resistant finish, which matters in slides because the extractor and striker channel are exposed to moisture, fouling, and cleaning solvents over thousands of cycles. Using factory-finished parts here reduces the risk of surface degradation that can affect extraction reliability over time.

Compatibility spans the full P320 platform in 9mm, .40 S&W, and .357 SIG, including M17 and M18 slides, which reflects the modular architecture the P320 was designed around from the start. If you are rebuilding a duty slide, refreshing a dedicated range upper, or finishing a custom P320 project, the internal geometry and dimensions match what Sig Sauer installs at the factory — no fitting, stoning, or modification required.
