The Sig Sauer P320 Full-Size pistol in 9mm with a black nitride finish (brand part no. 320F-9-BSSP-10) is a modular striker-fired pistol built on a full-size frame for a longer sight radius and full-hand grip, suited to duty, home defense, and range use. Sig Sauer ships the pistol optics-ready with a serrated slide, and Siglite night sights support low-light target acquisition. The 4.7-inch barrel extends sight radius over the compact variant, and two 10-round magazines ship in the box. Among full-size semi-auto handguns, this P320 Full-Size configuration favors shooters who want maximum sight radius and grip real estate.
