The Reserve submodel is part of SIG's Custom Works Reserve Collection and is marked Newington, NH, USA. This full-size P226 X-FIVE is built on a stainless steel frame and slide, both finished in a high-polish black DLC that pairs durability with a refined presentation.
The pistol uses a single-action-only operating system with an ambidextrous manual safety. Its SIG AX3 three-way adjustable competition trigger is flat-faced and tunable for pull weight, over-travel, and length of pull, allowing precise setup to the shooter.
The slide is optic-cut (cover plate screw holes visible) and includes front and rear serrations for confident manipulation. An integral slide-mounted expansion chamber with top ports is incorporated, and the pistol is equipped with iron sights featuring a green-dot front and a notch rear.
Controls and ergonomics include an extended beavertail, a flared magwell for faster reloads, and a sport-style takedown lever. The frame has an integrated rail, textured grid-pattern grips, a 4.4-inch barrel, and a standard capacity of 20+1 using steel, double-stack P226-pattern magazines. The included paperwork and MPN 226X5-9-CW-RES match the case and documents provided.
