The P211-GTO pairs a 4.4 in bull barrel with SIG's factory SIG-LOC Pro compensator to manage muzzle movement while keeping overall length compact. The full-length dustcover and 1913/Picatinny rail provide a rigid front end and mounting space for a light.
The steel frame and alloy grip module are matched with textured G10 grip panels and a large flared magwell for confident control and fast reloads. Controls include ambidextrous manual safeties and an ambidextrous slide stop.
The slide features forward and rear serrations plus a SIG-LOC Pro direct-mount interface and optic cut. It ships with a Sig Sauer Romeo-X Red Dot Optic installed, and the iron sights comprise a green fiber-optic front with a rear sighting reference via the optic.
This 9mm SAO, double-stack 1911-pattern pistol feeds from double-stack 1911/2011-style 21-round magazines (three included) for a 21+1 capacity. It is a recent release from SIG Sauer and is made in the USA.
