Building or customizing a Sig P365 means sourcing quality components that fit right the first time. The Rival Arms RA42P002A Slide Completion Kit delivers the parts you need to finish a P365 slide without the guesswork. Whether you're assembling a new upper, refreshing a worn slide, or matching upgraded internals to factory parts, this kit keeps you moving forward with components engineered to OEM tolerances.
Rival Arms specializes in Sig platform parts that work. The black PVD stainless steel finish resists corrosion and wear while maintaining a professional look that complements both duty and recreational guns. PVD coating is tougher than standard parkerizing and more durable than bluing, making it a smart choice for a component that sees regular handling and cleaning.
This is a completion kit—meaning it bundles the strikers, springs, and small parts that round out a slide assembly. If you're already comfortable with P365 takedown and reassembly, you know exactly what you're getting and why it matters. If you're newer to the platform, pair this with a quality armorer's manual or video guide to ensure correct installation.
