The SIG Sauer P320 Compact is a compact, duty-ready 9mm pistol that blends concealability with full-size ergonomics: it features a 3.6? threaded barrel (factory 1/2-28 RH), an X-Series polymer grip module for excellent hand feel and control, and an optic-ready X-slide topped with a factory ROMEO-RS Pro reflex sight and XRAY3 co-witnessable iron sights for fast, confident target acquisition. Striker-fired with SIG’s flat X trigger, the pistol ships with two 15-round steel magazines, includes a MIL-STD Picatinny rail for lights/lasers, and wears a durable Nitron finish on a steel slide — a versatile choice for everyday carry, range sessions, or as a compact duty gun that’s ready for suppressors or red-dot setups out of the box.
