The MK25 specification on this pistol includes phosphate-coated internals for corrosion resistance, a white USN-style anchor marking on the slide, and a UID data plate on the frame. The frame is marked "SIG SAUER INC., NEWINGTON-NH-USA," and the barrel hood is marked "9mm x 19." An AC proof/inspection mark is present on the frame above the trigger.
Construction is classic P226: a Nitron-finished slide over a hard-coat anodized aluminum alloy frame, with the standard DA/SA control layout featuring a decocking lever and slide catch. The pistol uses a smooth-face curved trigger and an exposed spur hammer. Rear-only slide serrations provide traction for manipulation.
Sights are fixed and dovetailed, with a white dot front. The dustcover carries a three-slot MIL-STD-1913 accessory rail. This is a full-size configuration with a 4.4 inch barrel and black textured polymer grip panels installed.
Chambered in 9mm Luger, the pistol has an 18+1 capacity and comes with six magazines: three 18-round and three 15-round stainless-steel SIG P226 magazines. The package is rounded out with two OWB Kydex holsters (including a duty-style holster with retention hood), a pair of textured tan grip panels, two reputable parts kits (Grayguns and Armory Craft), assorted small parts, and the serial-matched MK-25 factory case.
