SIG P211 Pistols
The SIG P211 is SIG’s double-stack 1911: a hammer-fired, single-action 9mm with a steel frame, an alloy grip module, ambidextrous thumb safeties, a grip safety, and P320 magazines. It keeps the 1911’s natural point and a straight-pull flat trigger, then feeds from magazines you can already find for a P320.
GTO is the compensated gun: a 4.4 in. bull barrel and SIG’s MACH3D compensator. GT4 is the carry-length P211 with a 4.2 in. barrel and no compensator. GT5 is the five-inch gun without a compensator. Factory ROMEO-X SIG-LOC Pro and ROMEO3 PRO packages sit on the SIG-LOC Pro cut, which is not a compact RMSc pistol sight.
How to choose
Black Nitron is the core finish. Combat and the coyote GT4/GT5 change the color. Equinox is the two-tone Custom Works GTO with alloy LOK grips. Ten-round pistols keep the same slide and change the magazines. These are serialized 9mm handguns and ship to a licensed FFL. See also SIG Sauer pistols.
