SIG Sauer 211CA-9-GT4-10 is the capacity-restricted P211-GT4: a single-action-only 9 mm Luger pistol with a 4.2-inch target-crowned bull barrel and a carry-length SIG-LOC PRO optic-ready slide. It ships with three 10-round P320-pattern steel magazines instead of the 17/21-round set.

The GT4 is SIG's compact-length, non-compensated P211. The frame is steel with a carry-length three-slot Picatinny rail; the grip module is alloy with G10 panels and a removable low-profile steel magwell. Controls are fully ambidextrous. Safeties are the 1911-style grip safety, ambidextrous thumb safeties, and a firing-pin safety. The trigger is a straight-pull skeletonized flat blade. Sights are XRAY3 day/night front with a black rear; the slide is optic-ready, not factory-dotted on this SKU.

Finish is black. This is a hammer-fired, short-recoil, mechanically locked pistol in the P211 double-stack 1911 family — not a P320 striker gun, even though it feeds P320 steel magazines.
