Features

The P365 is a striker fired, short-recoil handgun with a stainless steel slide, treated with a black Nitron finish, and a stainless steel frame along with a polymer grip module. The slide has serrations on both front and back for easy slide manipulation. The polymer grip accepts a double-stack 10-round, 12-round, or 15-round magazine. The magazine is released by a triangular button on the grip located at the undercut trigger guard section. Per SIG Sauer, the P365 has the lowest bore-axis ratio of any handgun currently made.Live broadcast from the 2018 SHOT Show Sights are green
