Sig Sauer P365X M81 Metal Comp 9mm 3.5″ Barrel 17-Round

Description

The P365X has always punched above its weight class as a micro-compact, and this M81 Metal Comp build shows exactly what happens when Sig's Custom Works team gets involved. At its core you still have the proven P365X platform: striker-fired action, a stainless steel Nitron slide with front and rear cocking serrations, and a SIG accessory rail below the barrel. What sets this version apart is the combination of parts most people spend months sourcing and building themselves. The metal grip module finished in M81 Woodland camo adds real substance to the handshake, contributing to better recoil management compared to the standard polymer grip. Paired with the Zaffiri Precision compensator on the 3.5-inch 416R stainless steel barrel, muzzle flip is noticeably reduced, which translates directly to faster, more controlled follow-up shots. The slide is optics ready with the optic channel cut separate from the rear sight dovetail, so you can run it as-is with the XRAY3 tritium day/night sights or drop a compact red dot on top without losing your irons.

What the Zaffiri Comp Actually Does on the P365X M81

Zaffiri Precision's threadless compensator design works by redirecting propellant gas downward through a 120-degree port opening, reducing muzzle climb through a combination of gas redirection and the added weight of the 17-4 stainless steel comp itself. The result on a platform this size is genuinely noticeable. The 3.5-inch 416R stainless match-grade barrel also gives you a slight sight radius advantage over the standard 3.1-inch P365X barrel, which helps at distance. The barrel is threaded, and the accessory rail opens up options for lights and lasers, making this a genuinely versatile carry or range setup without requiring you to track down and swap individual components yourself.

The M81 Metal Grip and Custom Works Configuration

The metal grip module here is not just cosmetic. Sig's own metal grips are engineered to enhance the balance of the pistol and the added mass helps absorb felt recoil, which is something you appreciate during extended range sessions. The M81 Woodland finish is a classic four-color camouflage pattern that gives this build a distinctly military-inspired look while still being a serious, hard-use pistol. This is a Sig Custom Works configuration, which means it ships with a pistol case and cable lock alongside the 17-round magazine. The XRAY3 sights are a 3-dot tritium system designed for fast target acquisition in any light condition, day or night, and the optics-ready cut means you're not locked in if you decide to add a red dot down the road.
