Rival Arms Optic Ready Slide A1 Sig P365 Black QPQ 416R Stainless Steel

Upgrade your carry or range Sig P365 with the Rival Arms Optic Ready Slide A1 - a match-grade precision slide CNC machined from 416R stainless steel billet for superior strength, corrosion resistance, and dimensional stability over a factory slide.

Purpose-built for shooters who want a quality optic-ready slide without going full custom, the A1 features recessed slide cuts engineered for direct compatibility with RMR-pattern red dot optics and similar reflex sights. Front and rear serrations provide a positive grip for press checks, chambering, and malfunction clearing. A black QPQ (Quench-Polish-Quench) thermo-chemical finish gives the slide a durable, low-glare matte surface that holds up to hard use.

Whether you are building out a P365 from the grip module up or swapping a worn factory slide for one with a purpose-built optic cut, the Rival Arms A1 brings premium materials, thoughtful features, and a clean optic-ready package to the popular Sig P365 platform.
