The SIG Sauer P320 has recently been adopted by the US Military, replacing the Beretta M9 which has been in use since 1985.  The SIG P320 is a striker-fired modular pistol, with interchangeable frames to adapting to the needs of a myriad of different shooters. Ranging from small to large-sized hands. The simplicity of the P320 is in being a striker-fired pistol that removes any obligation for decockers, safeties, and exposed hammers.  

When buying a factory SIG Sauer magazine, you are buying the confidence in a magazine that is designed specifically for hard use in the toughest of conditions for our Military and Law Enforcement, when the deployment of an ultra reliable firearm is extremely urgent.
