The Sig Sauer 1911 X-Series in 45 ACP pairs the timeless 1911 platform with modern optics-ready engineering—a full-size, 5-inch pistol designed for shooters who want classic ergonomics and proven reliability with the precision of a factory-installed red-dot sight. The coyote PVD finish over stainless steel gives it a rugged, working aesthetic, while the direct-mount ROMEO-X optic and traditional iron sights let you shoot with confidence in daylight or low light. Whether you're training on the range, competing, or trusting it as a duty or home-defense firearm, the 1911-X bridges generations of 1911 shooters and modern red-dot revolution users.
The Sig ROMEO-X red dot is built into this pistol from the factory—no hunting for a separate optic or wrestling with mounting. The sight uses a compact footprint (Shield RMS-c compatible) so it sits low enough to cowitness with the included XRAY3 day/night iron sights, giving you redundancy and flexibility. The ROMEO-X itself is machined from 7075 aircraft-grade aluminum, features a 2 MOA dot with a 32 MOA circle, and offers 15 brightness levels including night vision settings. Battery changes happen via a side-mounted CR1632 compartment without removing the optic from the gun.
The pistol itself handles like a 1911 should. The stainless-steel frame wears an undercut trigger guard, extended ambidextrous manual safety, and M1913 accessory rail. Custom G10 grips from LOK Grips (black) provide grip texture and control, while the black serrated flat trigger breaks cleanly in single-action. Slide serrations front and rear aid manipulation, a removable metal magwell speeds reloads, and the checkered front strap delivers traction without the snag. Two 8-round steel magazines ship with the gun, and the sight radius stretches to 6.5 inches for inherent accuracy.
At 42 ounces loaded, the 1911-X carries the weight expected of a steel-frame 45 ACP—substantial enough to manage recoil and run reliably, light enough not to fatigue during extended range sessions. The 8.7-inch overall length and 1.4-inch width make it a full-size platform, not a compact, so expect full grip-frame comfort and capacity. If you're drawn to the 1911's legacy but want a factory-fresh red-dot platform without the guesswork, this is a straight-shooting choice.

The system is integrated from the factory, and the battery compartment is accessible from the side without removing the sight.
No. The barrel is not threaded.
