The Army's New Sidearm: Sig P320
The Sig P320 is the US Army's new modular service pistol, replacing the Beretta M9. Sig Sauer secured a significant contract, highlighting the P320's adaptability through its serialized chassis system. This allows for easy caliber and frame size conversions, supporting 9mm, .357 Sig, and .40 S&W across various grip modules.
