Sig Sauer, P320 Compact, 45 Acp, 3.90 inch, 9+1, Nitron Slide, Stainless Steel Frame

The Sig Sauer P320 Compact 45ACP 320C45BSS brings the modular P320 series into a compact, duty-capable package that requires an FFL transfer and is built for carry, home defense, and range work, offering a 3.90" Black Carbon Steel barrel and a serrated Black Nitron slide over a black stainless steel frame with an integrated Picatinny rail for lights or lasers. As a striker-fired, 9+1 45 ACP pistol with Siglite night sights, a 25.8 oz weight and black polymer right-hand grips, this compact balances controllability with the stopping power of 45 ACP, while the polymer/stainless construction keeps durability and recoil management in check. The compact P320 footprint makes it comfortable for controlled carry and rapid follow-up shots during defensive drills, and the night sights and Picatinny rail make it practical for low-light duty scenarios. With no manual external safety, the internal striker-fired safety systems and serialized fire control unit inherent to the P320 series provide consistent trigger feel and interchangeable versatility for users who value modularity, reliability, and the proven ergonomics Sig Sauer delivers.
