Sig Sauer 365X9BXR3PRS P365 9mm Luger 12+1 3.10"
The Sig Sauer P365X is a micro-compact 9mm pistol built for serious everyday carry. At just over 6 inches long and weighing 17.8 ounces, it delivers real firepower in a frame small enough to disappear in a waistband or jacket pocket—without sacrificing shootability or capacity. The extended X grip module gives you a full firing grip despite the compact overall dimensions, and the flush-fit 12-round magazine means you're not printing a magazine well. This is the pistol that redefined what concealed carry could actually do.
The P365X ships with two 12-round steel magazines, ROMEO-RS Compact optics-ready slide with integrated XRAY3 day/night front sight, and Sig's renowned X flat trigger. The trigger itself has earned respect for its clean, crisp break—fast enough for defensive work, refined enough for precision shooting. The nitron stainless steel slide and frame are built for hard use, and the integrated SIG rail gives you mounting options for lights and lasers if your carry role demands it.
Optic-ready in the compact RMS-c footprint, the P365X lets you run a red dot sight for faster target acquisition at defensive distances or hunting applications. The 3.1-inch barrel and 4.9-inch sight radius deliver acceptable velocity and ballistics for 9mm Luger without the length penalty of a full-size duty gun. There's no manual safety—this is a striker-fired design that relies on a safe holster and trigger discipline, typical of modern concealed-carry pistols. Stripped down to essentials, it's one of the most capable micro-compact carry guns on the market.
