SIG Sauer P211-GT4 RXSL – 9mm, 4.2" Bull Barrel, SAO, ROMEO-X SIG-LOC PRO, Black (211CA-9-GT4-RXSL)
The P211-GT4 is SIG’s carry-length, non-compensated take on the P211 double-stack, single-action-only platform: a 4.2-inch target-crowned bull barrel under a carry-length SIG-LOC PRO optic-ready slide, on a steel frame with an alloy grip module. This configuration comes optic-equipped with a factory-mounted ROMEO-X SIG-LOC PRO, in black Nitron with black G10 grip panels, and ships with one 17-round and two 21-round steel magazines. SIG model 211CA-9-GT4-RXSL, UPC 798681740932. This listing is for the P211-GT4 with ROMEO-X SIG-LOC PRO, model 211CA-9-GT4-RXSL only.
Carry Length, Duty Grade
SIG built the GT4 to balance concealability and control: a traditional, non-compensated slide for predictable recoil, aggressive duty-style serrations, and fully ambidextrous controls. A removable low-profile steel magwell speeds reloads without adding carry bulk, and the skeletonized flat-blade trigger is a straight-pull, single-action design for a clean, repeatable break.
Optic Installed
The ROMEO-X SIG-LOC PRO mounts directly to the SIG-LOC PRO slide cut — SIG’s interface that uses multiple contact points between optic and slide to help hold zero under recoil. XRAY3 Day/Night iron sights remain on the slide as a backup.
Safety System
The P211 uses a grip safety, ambidextrous thumb safeties, and a firing pin safety. SIG’s guidance: a manual safety is designed to augment, not replace, safe handling — keep your finger off the trigger until you intend to fire.
Magazines
Ships with one 17-round and two 21-round P320-compatible steel magazines.
