The MK25 designation brings several Naval Special Warfare-identifying details. This pistol features the USN-style fouled anchor emblem on the slide and a factory UID label with MFR 1EF82 and PNO MK-25 plus 2D code. The frame is marked "SIG SAUER Inc., Newington NH USA," aligning with the model's U.S.-market lineage.
Its operating system is DA/SA with a decocking lever, paired with a spurred hammer for controlled manual operation. The standard, checkered magazine release offers positive engagement, and rear-only diagonal slide serrations provide purchase for administrative handling.
Sight regulation is handled by fixed, dovetailed sights, front and rear. A true 3-slot MIL-STD-1913 Picatinny accessory rail is machined into the dustcover, providing the standardized interface specified for the MK25 configuration.
This full-size 9mm includes a 4.4-inch barrel and a 15+1 capacity. Black textured polymer two-panel grips are molded with SIG SAUER and P226 logos, complementing the metal frame for a solid, duty-style feel. The slide carries the anchor emblem and rear serrations consistent with the series.
