Sig Sauer P320 Sxg 9mm 5 21Rd Romeo1 Pro Rail
The Sig Sauer P320 SXG 9mm is a full-size, all-steel competition pistol built for shooters who demand accuracy and control at the range or on the match stage. Developed in collaboration with Team SIG captain Max Michel, this 5-inch barrel pistol combines a stainless steel grip module with a custom slide design engineered to minimize felt recoil and maximize consistency. If you're serious about 9mm competition or high-volume range training, the P320 SXG delivers the precision and capacity you need out of the box.
The gun ships ready to go: a ROMEO3 MAX reflex sight is pre-installed on the PRO footprint optic plate, and you get four 21-round steel magazines right away. The custom wraparound serrations on the slide and aggressive grip texturing keep the pistol secure in your hand during rapid fire, while the Springer Precision magazine release and ambi slide release let you work the gun efficiently from either hand. The 5-inch carbon steel bull barrel and flat blade competition trigger support the kind of shot-to-shot precision expected in sanctioned matches.
Build quality is consistent with Sig's reputation: stainless steel frame and slide with Nitron finish, a solid one-piece 1911-style guide rod, custom Hogue aluminum grip panels, and M1913 accessory rail for lights or lasers down the road. The gun handles recoil well for a full-size 9mm, thanks partly to the included 14lb. and 16lb. recoil spring options so you can tune it to your ammo and shooting style.
