True Precision
The True Precision Axiom Slide with RMR cut for Sig Sauer P320 is a premium billet replacement slide built for shooters who want a modern optics platform without compromising on fit, finish, or durability. Machined from solid 17-4 stainless steel and heat-treated to spec, this slide pairs aggressive ergonomics with clean aesthetics in Stealth Gray—a professional choice for duty, sport, or serious carry use. It's factory-cut for Trijicon RMR and SRO optics and works seamlessly with popular micro red dots like Holosun's 407C, 507C, and 508T when paired with the correct mounting screws. Whether you're building a custom P320 or upgrading an existing frame, the Axiom gives you the precision and appeal that aftermarket slides are known for.
This slide is fully compatible with standard Sig P320 Compact, XCarry, and M18 frames (note: not compatible with XCompact models). It ships with an anodized optic cover plate, so you can carry and use it immediately even if you haven't selected your red dot yet. The design philosophy is aggressive without being tacky: reduced and scalloped front, angled rear serrations, and attractive window cuts give it character and function in equal measure. Everything is 100% US manufactured and designed by True Precision, a maker known for quality precision work in the custom P320 community.
Keep in mind that internal parts—firing pin, springs, extractors, and other small components—are not included; you'll be transferring these from your factory P320 slide or sourcing a complete parts kit separately. The Axiom Stealth Gray finish is engineered for both appearance and protection, giving your build a cohesive, modern look that stands out at the range or in a responsible carry setup.
