The SIG P320 10mm X-Series 5 Optic Ready is a full-sized, modern striker-fired pistol built for shooters who want real stopping power and flat-out capability. The 10mm cartridge delivers significantly more velocity and energy than 9mm or .45 ACP, making this gun a legitimate choice for hunting, backcountry defense, and serious sport shooting. The optic-ready slide gives you the flexibility to mount a red dot or other reflex sight, while the factory X-RAY3 day/night sights keep you effective in any light. This is a modular design—swap grip modules to fit your hand and shooting style—so you're getting a platform that adapts to you.
The X-Series flat trigger breaks clean at 90 degrees, giving you a predictable, repeatable press without creep. The 5-inch bull barrel is accurate out of the box and contributes to the 34.9-ounce feel—substantial enough to tame recoil but still manageable for carry or extended range sessions. The Coyote Brown finish on the stainless steel slide pairs tactical aesthetics with real corrosion resistance. Two 15-round magazines ship with the gun, so you get solid capacity out of the factory.
Whether you're upgrading from a 9mm to experience the terminal performance of 10mm, setting up a competition or hunting rig, or building a truck gun that can handle predator duty, the P320 10mm X-Series earns its place on the bench and in the field. The modular P320 platform is one of the most customizable and reliable striker-fired systems made, and 10mm chambers it in a full-size package that actually runs.
