SIG SAUER® P320 RXP Full-Size 9mm Semi-automatic Pistol with Romeo1 PRO Reflex Sight

Designed for the unique demands of today's law enforcement and military professionals, the SIG SAUER P320 is built around a serialized modular frame and striker-fired operating system. This allows for changes in caliber and size without compromising functionality, accuracy or reliability (caliber conversion kits and extra grip modules sold separately).

It's that versatility and adaptability—along with classic SIG ergonomics and reliability—that made it a natural choice as the U.S. MIlitary's main service pistol. This particular model comes with a Romeo1 PRO Reflex Optic, factory-mounted and factory-zeroed for out-of-the-box accuracy. It's the total package: great trigger, exceptional accuracy, military-grade durability…and the nice optic is the icing on the cake.
