The Sig Sauer P320 Full Size pistol in 9mm and black finish (brand part no. 320F-9-BSSP) pairs a stainless steel frame and slide with a factory optic-ready cut using Sig’s PRO optic footprint, giving duty and competition shooters direct red dot mounting on a full-size platform. Sig Sauer coats the 4.7-inch carbon steel barrel in DLC for durability, and SIGLite night sights provide reliable low-light aiming with or without a mounted optic. The Nitron-finished slide is serrated for reliable manual manipulation, and the full-length accessory rail supports mounted lights and lasers; two 17-round magazines ship in the box. Among full-size semi-auto handguns, this P320 Full Size configuration favors duty shooters who want maximum capacity with night-sight readiness.
