Rival Arms Optic Ready Slide A1 for Sig P365 - Black 416R Stainless Steel (RA10P001A)

Building a custom Sig P365 means starting with a quality foundation, and the Rival Arms Optic Ready Slide A1 is engineered to deliver exactly that. This precision-machined slide is CNC-cut from 416 stainless steel billet, then hardened via Quench-Polish-Quench (QPQ) thermo-chemical treatment to handle the wear and corrosion that come with regular carry and shooting. The optic-ready design means you can mount a red dot or other compatible sight directly to the top—no gunsmithing required to modernize your P365.

The A1 design keeps details practical: front and rear serrations give you confident purchase when racking the slide or performing press checks, while window cuts along the side reduce weight and improve cooling under sustained fire. Every slide is individually hand-inspected at Rival Arms to ensure fit and finish meet their match-grade standard. This is the kind of component that feels right the moment you work the action—smooth, tight, and clearly built to last.

Whether you're upgrading a stock P365, building a competition gun, or customizing a carry setup with modern optics, this slide gives you the precision foundation serious shooters expect. It ships in black and integrates with the existing P365 ecosystem—a purpose-built part for a platform that deserves one.
