True Precision Slide for Sig Sauer P365XL - RMS Cut, Copper Finish

The True Precision Slide for Sig Sauer P365XL with RMS Cut is a complete, stripped replacement slide engineered and manufactured entirely in the USA. If you're building a custom P365XL or upgrading from the factory slide, this billet-machined option gives you a platform designed for defensive use with a modern optics footprint. Cut for Shield Arms RMS series red dots—including the RMS, RMSc, RMSw, and SMS—it's ready to mount a compact reflex sight or run iron sights with the included anodized black optic cover plate.

Every True Precision slide starts as solid 17-4PH certified steel, machined and heat-treated to specification. The copper finish sets this version apart visually while delivering the same durability and precision fit. Design details include aggressive front-end scalloping and serrations angled at the rear, both practical touches that enhance handling and grip. Side and top cut windows lighten the slide without compromising rigidity—a hallmark of custom P365XL builds aimed at concealed carry or defensive readiness.

This is a finished, stripped slide with no barrel, firing pin, or internals—you'll need to source those separately or transfer them from an existing slide. It arrives with mounting hardware for the optic cover plate, so you're set whether you plan to add a red dot immediately or keep irons for now. True Precision's commitment to American manufacturing and design means you're investing in domestic quality backed by a maker with a clear defensive-first philosophy.
