The MK-25 configuration delivers the full-size P226 performance in 9mm Luger with a DA/SA action and decocker. It uses an alloy frame paired with a stainless-steel slide, all in a matte black finish, and wears textured black polymer grip panels for a solid, repeatable hold.
Built for enhanced durability, this pistol includes phosphate-treated internal components and a chrome-lined 4.4-inch barrel. The frame is marked "SIG SAUER INC., NEWINGTON–NH–USA," and the overall finish is a uniform matte black that complements its duty-ready configuration.
Sighting is handled by fixed SIGLITE night sights in a three-dot arrangement, with both front blade and rear notch set in dovetails. The dustcover hosts a true MIL-STD-1913 three-slot Picatinny rail for mounting compatible accessories.
Naval identifiers set this example apart: a USN-style anchor is engraved on the slide, and the left dustcover carries a UID label showing CAGE code 1EF82 and PNO MK-25. The UID label matches this pistol. The factory case label is dated May 26, 2026, aligning it with recent production.
Capacity is 15+1, and this pistol arrives with three 15-round Mec-Gar steel magazines. The combination of the corrosion-resistance package, night sights, and correct MIL-STD-1913 rail makes this MK-25 a well-specified example of the P226 platform.
