The Sig Sauer P320 series pistols are renowned for their modularity, accuracy and reliability. The ability to interchange frames to suit the shooter's hand, while retaining the same fire control group, represents a significant advancement. The P320 was chosen as the new sidearm for the US military and adopted as the M17 pistol, largely due to its frame modularity. Available in various grip sizes to cater to user preferences, the Carry Grip Module integrates the magazine release and is compatible with models in 9mm, .40 S&W and .357 Sig with a manual safety. It also features a molded-in picatinny rail for attaching lights or lasers.
