Sig Sauer P365 9mm Pistol, 3.1" Barrel, 10-Round Magazine, Manual Safety - 365-9-BXR3P-MS

The Sig Sauer P365 9mm pistol is a striker-fired micro-compact designed for shooters who demand serious concealed-carry performance without compromise. This 3.1" barrel model chambers 9mm Luger and is rated for +P ammunition, giving you flexibility in ammunition selection for defensive or training use. At just 17.8 oz and measuring 5.8" overall length, the P365 delivers genuine carry-ability in a package that doesn't sacrifice shootability or capacity.

What sets this P365 apart is factory optic-readiness—the slide is cut and ready for direct mounting of a ROMEOZero Elite optic, opening up modern aiming options without aftermarket gunsmithing. The manual safety variant gives you an extra layer of security for daily carry, appealing to those who prefer an engaged safety on a defensive pistol. You get XRAY3 Day/Night sights right out of the box, a feature that justifies the P365's reputation as one of the most versatile micro-compacts on the market.

This particular model ships with two 10-round steel magazines—one flush-fit for minimal profile carry, one extended for range work or home defense. The Nitron-finished stainless slide resists corrosion, while the modular polymer grip module and SIG Rail accessory interface give you customization options down the road. Whether you're a first-time concealed carrier or a seasoned shooter looking for a reliable backup gun, the P365 striker-fired trigger delivers the clean, predictable break Sig is known for.

State-compliant versions are available for CO, CT, HI, IL, and NJ, making the P365 accessible to carriers in restrictive jurisdictions. Optional 12-round and 17-round extended magazines are available separately if you want more capacity for specific use cases.
