Sig Sauer P365 9mm 3.1 X-Series 12Rd Sig-Loc

The Sig Sauer P365 9mm is a micro-compact pistol designed for shooters who refuse to compromise between firepower and concealability. This X-Series variant pairs the proven 3.1-inch barrel platform with modern duty features like X-RAY3 day/night sights and factory-installed ROMEO-X SIG-LOC optics compatibility—making it equally at home as a carry gun, home-defense piece, or range shooter's no-nonsense choice. At just 18 ounces loaded, it sits between true pocket pistols and full-size 9mms, offering the balance that serious users want.

The P365 X-Series arrives ready to work. You get two 12-round steel magazines in the box, more capacity than you'd expect from a frame this compact. The SIG Rail under the dust cover accepts weapon lights and accessories, the flat striker trigger is tuned for consistent breaks, and the stainless steel construction resists corrosion in the field. The sight radius reaches 4.9 inches despite the short slide, meaning you can run accurate drills and transitions without fighting the gun's geometry.

Optics-ready out of the box with the SIG-LOC compact footprint already milled and pre-installed with the ROMEO-X, the P365 9mm adapts to modern shooting preferences without aftermarket gunsmithing. Whether you're running the included irons or mounting a dot, this gun is built to be pushed hard. Nitron-finished slide over stainless internals, polymer grip module in black, and a trigger that breaks clean—this is Sig's purpose-built answer for shooters who carry 9mm seriously.
