The SIG P211 GTO gives the timeless features and performance driven design of double-stack 1911 pistols a modern twist. The P211 GTO pairs a 4.40 bull barrel with the Mach3D compensator. This 3D-manufactured compensator uses a specialized gas flow design to dramatically reduce muzzle rise and felt recoil, allowing for faster, more accurate follow-up shots. Features a full-length dust cover; straight-pull trigger; removable steel magwell; SIGLOC PRO optic ready slide; a grip safety, ambidextrous thumb safety and a reliable firing pin safety. The P211 has been engineered to use the P320 magazine. Includes a ROMEOX Pro, 21rd and a 23rd magazine.
