Description
The Sig Sauer 1911 X-Series 45 ACP 5″ Optic-Ready Coyote takes the classic 1911 platform and updates it with modern features for duty, competition, and range work. Chambered in .45 ACP with a 5-inch barrel, this full-size pistol comes optics-ready from the factory, with a coyote PVD finish on the stainless frame and slide. It ships with two 8-round steel magazines and XRAY3 day/night sights, giving you a reliable, shootable 1911 that’s built to run with a red dot.

Who It’s For
This pistol is built for shooters who want a traditional 1911 feel but need modern upgrades: red dot compatibility, better ergonomics, and factory reliability. It’s ideal for competition shooters in USPSA Single Stack or IDPA CDP, duty use where a .45 is required, or range enthusiasts who want a premium optics-ready 1911 without the custom shop wait.
Pros and Cons
- Pros: Optics-ready out of the box; excellent XRAY3 night sights; undercut trigger guard improves grip; removable magwell adds versatility; coyote PVD finish resists holster wear.
- Cons: Does not include an optic mounting plate—you’ll need to buy one separately (e.g., Sig Sauer’s own plate or third-party). The grip safety is not adjustable, which may not suit all hand sizes.

FAQ
Does the Sig Sauer 1911 X-Series come with an optic mounting plate?
No. The slide is milled for a common footprint (typically DeltaPoint Pro or similar), but the pistol does not include a mounting plate. You’ll need to purchase a plate separately from Sig Sauer or a third-party manufacturer.
Can I use standard 1911 magazines in this pistol?
Yes. It uses standard 1911-style 8-round magazines. The included steel mags are reliable, but aftermarket options from Wilson Combat or Chip McCormick also work.
Is the coyote PVD finish durable?
Yes. PVD (Physical Vapor Deposition) is a tough, wear-resistant finish. According to Sig Sauer specs, it holds up well against holster wear and corrosion.
What optics fit the X-Series slide?
The slide is cut for the Sig Sauer Romeo1Pro and DeltaPoint Pro footprint. Other optics like the Leupold DPP or Holosun 507C (with adapter plate) may fit with the correct plate.
Is this pistol California-compliant?
No. The Sig Sauer 1911 X-Series is not on the California Roster of Handguns Certified for Sale. It ships with standard-capacity magazines.
