Rival Arms RA42P001A Slide Completion Kit for Sig P320 - Black PVD Stainless Steel

Building or customizing a Sig P320? The Rival Arms RA42P001A Slide Completion Kit for Sig P320 gives you the precision-machined components needed to finish your slide assembly with confidence. Whether you're a gunsmith, competitive shooter, or serious tinkerer, this black PVD stainless steel kit delivers the quality and durability expected from a purpose-built P320 parts supplier. Rival Arms engineered this kit to tight tolerances, so each component works reliably with OEM and aftermarket P320 platforms.

Black PVD (Physical Vapor Deposition) stainless steel finish resists corrosion and wear far better than standard bluing or parkerizing, making it ideal for shooters who demand longevity in their builds. The stainless steel substrate ensures strength and dimensional stability across temperature and humidity swings—critical when precision fit matters. This is the real deal for serious P320 builds, not a compromise parts-bin solution.

Rival Arms has built a reputation among AR and pistol customizers for attention to detail and correct specifications. This kit reflects that focus: it's engineered to work, not to look pretty and fail. If you're assembling a P320 from components or replacing worn internals, this kit covers the essentials with parts designed to function together as a system.
