The Sig Sauer P320 Full Size .45 Auto is arguably the most adaptable service pistol design ever created. Its modularity allows the shooter to customize the gun for any mission. An interchangeable frame allows for a personal fit for a wide range of hand sizes. Its ability to change caliber, fit, and size, give the Sig Sauer P320 Full Size ultimate flexibility for the shooter. Its striker fired design uses a 5-point safety system, all while giving the shooter the edge with a surprisingly crisp trigger pull. The Sig Sauer P320 .45 auto has no external safety or decocking lever to snag or hang on the draw. A Mil-Std M1913 Picatinny Rail allows for lights and other accessories, while an ambidextrous slide catch and a reversible magazine release make for easy operation for both left, and right handed shooters. 3-Dot SIGLITE night sights give you the advantage in less than ideal lighting conditions. The Sig Sauer P320 semi-auto handgun is proudly made right here in the U.S.A.
