Rival Arms RA10P301A Optic Ready Slide for Sig P320 Carry, RMR Cut, QPQ Black, 416R Stainless Steel

The Rival Arms RA10P301A optic-ready slide for Sig P320 Carry is a precision-engineered match-grade upgrade that transforms your carry gun into a modern, optics-mounted platform. Built from 416 stainless steel and CNC machined to exacting tolerances, this slide handles the recoil forces and daily wear of a duty or self-defense handgun without sacrificing accuracy or reliability. The RMR-cut footprint accepts the Trijicon RMR and other direct-fit optics, with a cover plate included for situations where you run iron sights only. No gunsmith required—it's a straightforward swap on any compatible P320 Carry frame.

Rival Arms treats durability seriously. The slide undergoes Quench-Polish-Quench (QPQ) thermo-chemical hardening, which hardens the steel surface far beyond what a standard heat treat achieves, resisting wear from slide racking, holster friction, and years of function. The 416 stainless material itself resists corrosion, a crucial trait in carry guns exposed to sweat and moisture. Each slide is individually hand-inspected for accuracy before it ships, so you're getting a tight tolerance part, not a mass-production lottery ticket.

The RA10P301A is machined with purpose: front and rear serrations give you reliable purchase when manipulating the slide under stress, while window cuts along the barrel reduce weight and improve cooling without compromising structural integrity. If you're building a P320 Carry for competition, home defense, or upgrading your everyday carry gun, this slide delivers the fit, finish, and performance that separate a true upgrade from a gimmick.

Frequently Asked Questions

Will this slide fit my Sig P320 Carry without gunsmith work?

Yes. The RA10P301A is engineered as a direct replacement for the P320 Carry slide and requires no gunsmith installation on compatible frames.

What red dot sights are compatible with the RMR cut?

The RMR-cut footprint is designed for the Trijicon RMR and other optics that use the same direct-mount pattern. An optic cover plate is included if you want to run iron sights or swap optics.

Why does the slide have window cuts?

The window cuts reduce slide weight and improve airflow around the barrel for more efficient cooling during extended shooting sessions, while maintaining the structural integrity needed for reliable function and durability.

What's the difference between QPQ hardening and standard heat treat?

QPQ (Quench-Polish-Quench) is a thermo-chemical case-hardening process that creates a significantly harder surface layer than conventional heat treat, providing superior resistance to wear, abrasion, and corrosion—especially important for a carry gun.
