Rival Arms Sig P320 XFIVE Slide RMP Ready Black

The Rival Arms Sig P320 XFIVE Slide RMP Ready in Black is a match-grade precision upgrade slide engineered for the Sig Sauer P320 platform, specifically the XFIVE competition variant. This slide serves as the foundation of a custom P320 build, combining modern design with broad compatibility across the P320 ecosystem and a wide range of aftermarket optics and accessories.

The RMP-ready design incorporates recessed slide cuts that accommodate Trijicon RMR® red dot optics and other footprint-compatible sight systems, eliminating the need for external mounting plates. The slide is manufactured to match-grade tolerances, ensuring consistent cycling and optimal reliability when paired with compatible fire control groups and barrels. The 0.76 lb weight and compact profile (3 x 1.65 x 9.35 inches) reflect Rival Arms' focus on precision engineering without excess material, critical for shooters who prioritize repeatability and sight picture control in tactical and competitive scenarios.

This Sig P320 slide is purpose-built for operators, competitive shooters, and gunsmiths building or upgrading modular P320 pistols. The XFIVE variant is particularly suited to competition shooting disciplines where optic-ready configurations, ergonomic geometry, and proven reliability are non-negotiable. Whether you're assembling a duty weapon, a competition platform, or a training system, the Rival Arms P320 XFIVE slide pairs with standard P320 lower receiver groups and provides the precision foundation serious builds demand.

Rival Arms has established a reputation in the precision pistol slide market for delivering components that emphasize performance over cost-cutting. The black finish and match-grade construction position this slide at the professional and enthusiast tier of the P320 aftermarket, where consistency and optic compatibility are baseline expectations rather than premium features.
