The True Precision Axiom Slide is a precision-engineered, fully functional replacement slide for SIG SAUER P320 pistols, available in Black DLC finish with an RMR optic cut already machined in. Built from solid billet 17-4PH certified stainless steel and heat-treated to spec, this slide transforms your P320 into a modern, optics-ready platform without waiting for custom gunsmithing. It's manufactured and designed in the USA, giving you a quality upgrade you can trust for defensive carry, competition, or range work.

The Axiom slide is fully compatible with P320 Standard, Compact, XCarry, and M18 variants—though it won't fit the XCompact. The RMR cut comes ready for Trijicon RMR and SRO optics; it also accepts Holosun 407C, 507C, and 508T sights when fitted with the correct screws. A machined optic cover plate is included for situations where you run the slide optics-less, keeping debris out of the cut. The Black DLC finish delivers a clean, low-glint aesthetic that works equally well on a duty gun or a tricked-out competition build.

Aesthetics matter too: the Axiom features aggressive, reduced scalloping on the front end and angled rear serrations that improve grip and control. The distinctive window cuts give the slide a refined, purpose-built look. Note that internal parts—firing pin, springs, and components—are not included; you'll use the internals from your existing P320 slide or source them separately.
