The SIG Sauer P365X is designed from the ground up to be a micro compact concealed carry handgun with a magazine capacity similar to some sub-compact guns. This P365X pistol comes with two flush fit 12 round magazines all in a polymer pistol so small that practically disappears while you are carrying it until the moment you need it. Unlike most handguns that are designed and then have magazines built to work with them, the SIG Sauer P365 was built around the proprietary magazine. This unorthodox design process allowed SIG to create an innovative, reliable, double stack magazine in order to achieve their goal of 12 rounds in a micro compact pistol. Although, the polymer frame and stainless-steel slide were not just an afterthought. It was purpose built to be carried comfortably every day. The slide has been completely streamlined, getting rid of all sharp edges and features a beveled front to facilitate safe holstering. The aptly named P365 is so nice to carry, you will want to carry it all year long.

The SIG P365 comes right from the factory with XRAY3 day and night sights already installed as well as the Romeo Zero 3 MOA red dot sight. Right out of the box, this handgun is ready to carry. The polymer frame features a texture that is comfortable to hold while still giving plenty of grip and is slightly undercut on the trigger guard, so you can get a high grip for better control. It also utilizes the SIG proprietary accessory rail for attaching a light or laser depending on your preference for a carry gun.

The Nitron finished slide and internal frame provide an extra layer of wear and corrosion resistance and the 3.1” barrel is rated for +P ammunition. The XSeries striker fired flat faced trigger features a crisp break with a positive reset, allowing you to be extremely accurate. Included in the box is two 10 round magazines, all you need is a holster and you are ready to carry.
