SIG 1911 Pistols

The SIG 1911 is SIG’s steel single-stack .45. The classic 1911R keeps stainless, rosewood, and SIGLITE on a 5 in. SAO pistol. 1911-X is the same 1911 idea in the red-dot era: optic-ready compact footprint, XRAY3 day/night sights, LOK G10, a detachable magwell, and a flat trigger. Full-Size is the 5 in. gun. XCarry is the 4.2 in. gun. Factory ROMEO-X Compact sits on select pistols.

The optic cut is SIG’s compact footprint — ROMEO-X Compact / Shield RMSc family, not a full-size plate and not SIG-LOC. A factory red dot is not installed on optic-ready guns. Handguns ship to a licensed FFL. See also SIG pistols, SIG P211 for the double-stack 1911, and SIG ROMEO-X.

Factory ROMEO-X Compact is already on the ROMEO-X pistols. Off-Duty guns are credential-limited. Freedom two-tones are the black-and-white and bronze-and-black X-Series finishes.
