Description
SIG Sauer P211 GTO ROMEO-X SIG-LOC Pro 9mm Pistol, 4.4" Barrel, Black, 23/21-Round, Compensated
The SIG P211 GTO ROMEO-X 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 P211. SIG pins a MACH3D compensator on a 4.4 in. bull barrel so the gun stays flatter in a string. The slide is SIG-LOC Pro optic-ready. Controls are fully ambidextrous. A removable steel magwell ships on the gun.
This ROMEO-X GTO
SIG mounts a ROMEO-X SIG-LOC Pro at the factory and fits XRAY3 day/night sights. Height is 6.25 in. Weight is 46.7 oz. Magazines are one 23-round and two 21-round P320 steel mags. SIG-LOC Pro is SIG’s enclosed, bottom-mount pistol interface, not a drop-in RMSc.
What ships
The compensator and 4.4 in. bull barrel match the iron-sight GTO. The factory red dot is the difference. This pistol ships to a licensed FFL.
