Description
SIG Sauer P211 GT4 ROMEO-X SIG-LOC Pro 9mm Pistol, 4.2" Barrel, Black, 17/21-Round
The SIG P211 GT4 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.
GT4 is the carry-length P211. No compensator. A 4.2 in. bull barrel, a shorter slide, and a low-profile magwell so the pistol hides easier than a GTO while still taking P320 magazines.
This ROMEO-X GT4
SIG mounts a ROMEO-X SIG-LOC Pro at the factory. Height is 6 in. Weight is 42.3 oz with a magazine. Magazines are one 17-round and two 21-round P320 steel mags. There is no compensator on this carry slide. SIG-LOC Pro is not a drop-in RMSc.
What ships
