Sig Sauer 1911XR-45-SS | 1911 X-Series | .45 ACP

The Sig Sauer 1911XR-45-SS is a modernized full-size 1911 that pairs traditional steel construction with contemporary features: an optic-ready XSeries slide, XRAY3 day/night sights, and custom G10 grip panels. It ships with two 8-round steel magazines and includes an ambidextrous safety and extended slide release for ergonomic control. The pistol is configured as a single-action-only platform and includes an M1913 accessory rail for lights or lasers. For a direct-mount red-dot that stays well under $1,000, consider the Holosun 507K compact reflex sight for a low-profile, proven pairing.
