The Sig Sauer P365 9mm slide completion kit brings you factory-spec internal parts to restore or build out a P365, P365X, or P365XL slide. If you're a gunsmith, armorer, or experienced builder working on a platform that demands precision internals, this kit delivers the corrosion-resistant components Sig engineered for the job—all sourced directly from the manufacturer.
This slide completion kit includes the critical fire-control and extraction components: extractor assembly with pin and springs, the full striker group, striker safety and spring, and rear slide cap. It's designed to work as a complete system, so each part is engineered to function together. That's important—these are not field-strip-level components; installation requires full disassembly and technical know-how to do safely.
Sig Sauer is clear about one thing: this kit should be installed by a certified Sig Sauer armorer. Improper installation can lead to malfunction or serious injury. If you're not trained to do this work, don't attempt it; send the slide to a qualified gunsmith. Warranty coverage does not extend to damage from incorrect installation, and Sig charges for repairs needed due to improper assembly.
Bear in mind: the kit does not include barrel, sights, or recoil assembly—those are separate. Also note the guide rod is not part of this package, so plan accordingly when sourcing parts.
