SIG P365 / P365X 3.1" – Optic Cut Slide – RMSc Footprint – Stealth Grey Axiom


PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

The True Precision Axiom Slide is a premium replacement slide for the 3.1" SIG P365 / P365X 9mm platform, built in Stealth Grey with an RMSc-pattern optic cut and matching cover plate setup. It gives you a clean optics-ready upper with aggressive serrations, lightening window cuts, and a more refined look than the factory slab of metal SIG handed out on a Monday morning.

This specific version is the Stealth Grey finish with an RMSc footprint optic cut. It is built for the standard 3.1" P365 / P365X size family and includes the optic cut cover plate.

  • Fits 3.1" SIG P365 9mm pistols
  • Fits 3.1" SIG P365X 9mm pistols

What it does

This slide replaces your factory slide with an optics-ready Axiom cut unit that gives you improved front and rear grasping surfaces, reduced mass from the windowed design, and a built-in path to mount common RMSc-footprint micro optics without needing aftermarket machining.


Why it’s worth it

If you want to modernize a P365 without sending your OEM slide off for milling, this is the clean route. You get USA-made 416R stainless construction, sharper styling, real optic compatibility, and a finish that looks serious without screaming for attention like a mall-ninja trophy piece.

Install notes

This is a fitment- and function-critical upper component. Verify your exact pistol model, barrel length family, optic footprint, and parts compatibility before ordering. If you are building from a stripped setup or mixing aftermarket internals, do not assume every part stack plays nice just because the internet said “send it.”


Verify before you buy

Verify you have a 3.1" SIG P365 or P365X in 9mm, not the .380 ACP version. Verify your optic uses the RMSc footprint or is specifically listed by the manufacturer as compatible with this cut.
