Built as part of the Custom Works Reserve Collection, this P226-XFIVE Reserve is U.S.-made in Newington, NH, and marked by its premium construction and finish. Both the slide and frame are stainless steel with a high-polish DLC treatment, delivering a uniform, mirror-like appearance over a full-size profile. The pistol uses a 4.4 in barrel and ships with a factory test target dated March 3, 2025, and a matching case label dated March 4, 2025.
The operating system is single-action only with an ambidextrous manual safety and a reversible magazine release. SIG’s AX3 flat-faced trigger provides user adjustability for pull weight, over-travel, and length of pull. GridLOK alloy grip panels offer a secure, rigid interface, complemented by an extended flared magwell for quick magazine changes.
Slide features include front and rear serrations and a slide-integrated compensator/expansion chamber with ports; the barrel itself is not ported. The slide is cut for optics in the PRO footprint and comes with a cover plate that carries a click-adjustable rear sight. The pistol wears X-RAY3 day/night suppressor-height irons, with a tall front post featuring a green ring/dot and a black adjustable rear.
The frame is configured for control and consistency, with an extended beavertail, an undercut trigger guard, and a checkered front strap. An M1913 accessory rail with four slots is machined into the dust cover. Dimensions and capacity are full-size and duty-ready: overall length 8.6 in, height 6.0 in, width 1.7 in, unloaded weight 48.1 oz, and a 20+1 capacity using the included 20-round magazines.
