The MK25 configuration includes factory identifiers tied to its Naval lineage: the anchor emblem engraved on the slide and a frame-mounted UID/data-matrix label showing "PNO MK-25." The frame is rollmarked "SIG SAUER INC., NEWINGTON–NH–USA," and the barrel hood is stamped "9mm x 19."
This full-size P226 uses an alloy frame in matte black with a matching matte-finished slide. It is a DA/SA, hammer-fired, locked-breech pistol with a decocking lever and a spur hammer, delivering the classic P226 manual of arms and control layout.
Sighting is via fixed 3-dot sights with a drift-adjustable rear blade marked with height code 8. The dust cover features a true four-slot Picatinny accessory rail for mounting compatible lights or accessories.
The pistol currently wears textured, layered G10-style two-piece grip panels in tan/black. Both OEM grip sets are included: the classic two-piece black polymer panels and the one-piece E2 wraparound module, along with the E2 grip tool, giving multiple factory-correct grip options.
Capacity is 15+1 in 9mm Luger. Three 15-round steel magazines are included and are marked "Made in Italy" with witness holes. This example is made in the USA and retains the MK25-defining features buyers look for.
