SIG SAUER 1911 X-FULL .45 ACP 5″ ROMEO-X | MFG# 1911XR-45-BXR3-RXX

The SIG SAUER 1911 X-Series brings modern optics readiness and upgraded ergonomics to the classic 1911 platform. This full-size .45 ACP model features a 5″ barrel, an optic-ready XSERIES slide with a factory ROMEO-X compact red dot installed, XRAY3 day/night sights, extended controls, and two 8‑round steel magazines. For users who prefer a dedicated optic, the factory ROMEO‑X Compact pairs directly with the slide; it is a compact red-dot option that complements the platform.

Typical applications include precision range work and competitive pistol matches where a low-profile optic and refined ergonomics improve sighting speed and follow-up. The configuration also suits experienced shooters looking for a sight-ready, full-size .45 ACP service pistol for accurate target shooting.
