Sig Sauer P320 320C9Bssp 9Mm 3.9 Or 15R Blk

The Sig Sauer P320 is a striker-fired 9mm pistol built on the modular platform that has earned trust across law enforcement and civilian shooters alike. This compact version pairs a 3.9-inch carbon steel barrel with DLC coating to a medium grip module, delivering a balance of shootability and concealability that works for duty carry, backup roles, or personal defense. The stainless steel slide and frame with Nitron finish stand up to daily handling, and the optic-ready slide accepts Sig's PRO optic footprint—no gunsmithing required if you decide to add a red dot down the road.

What sets the P320 apart is its modular design: you can swap grip modules, barrels, and slides to customize the gun for your needs. This particular configuration comes set up for someone who wants a reliable, versatile compact 9mm without compromise. The medium grip module gives you enough purchase for control while keeping the overall footprint manageable. Two 15-round magazines ship with the gun, giving you solid capacity for a compact frame.

Sig's SIGLite night sights are already installed, so you're ready to shoot in low light out of the box. The curved striker-fired trigger breaks cleanly, and the accessory rail up front means you can mount a light if you're running this for home defense or tactical work. Whether you're looking for a P320 compact for concealed carry, range work, or a versatile duty pistol, this is a no-frills, purpose-built choice.
