Rival Arms Precision Slide with Front/Rear Serrations & RMS Cuts QPQ Black 416R Stainless Steel for Sig P365

Building a reliable Sig P365 starts with a quality slide—and the Rival Arms Precision Slide with Front/Rear Serrations and RMS Cuts is purpose-built to elevate your compact 9mm platform. This match-grade precision slide is CNC machined from 416R stainless steel billet, offering the durability and corrosion resistance serious shooters expect. Whether you're upgrading for carry, duty, or competition use, this slide combines modern design with practical ergonomics and broad parts compatibility.

The optics-ready footprint includes factory milling for RMS (Rival Micro System) red dot mounts, giving you the flexibility to run a modern pistol optic without custom gunsmithing. The slide ships with a cover plate, so you're ready to install your sight immediately or swap between irons and glass as your setup evolves. Front and rear serrations provide positive grip purchase for slide manipulation—critical if you're training or using this pistol in any serious capacity. Window cuts along the sides improve cooling and airflow without compromising structural integrity.

Rival Arms finishes this slide using QPQ (Quench-Polish-Quench) thermo-chemical case hardening, a proven process that hardens the exterior while preserving the integrity of the underlying steel. That means your slide resists wear and corrosion better than standard finishes. Every slide is individually hand inspected for accuracy before it ships, so you know you're getting a precision component—not a lottery ticket. Installation requires no gunsmith; this is a direct fit for the P365 platform.
