Sig Sauer 1911 X-Series Full Size | .45 ACP | 5in | 1911XR-45-CXR3

The Sig Sauer 1911 X-Series is a full-size, single-action-only 1911 platform finished in Coyote PVD and chambered in .45 ACP with a 5-inch barrel. It pairs modern features—an optic-ready XSERIES slide with a compact Shield RMS-C footprint and XRAY3 day/night sights—with classic 1911 ergonomics, including an extended ambidextrous safety and an XSeries flat trigger. This configuration ships with two 8-round steel magazines and a removable metal magwell for improved reloads.

Suggested optic: a Shield RMSc footprint red dot (Shield RMSc) is a straightforward, sub-$1,000 option that complements the X-Series optic cut while keeping sight picture low and durable for range and competition use. Typical applications for this pistol include precision target/range work and competition shooting where a full-size 1911 platform and an optic-ready slide deliver practical benefits.
