The Sig Sauer P226 MK25 full-size 9mm pistol is built on the same design that earned the trust of U.S. Navy SEALs and has defined the standard for combat handguns for decades. This is serious duty-grade hardware: a full-size frame paired with a 4.4-inch barrel that delivers reliable accuracy and ballistic performance you can count on in the field or at the range. The MK25 combines proven ergonomics with a modern tactical platform—the kind of pistol that works equally well for home defense, sport shooting, or professional carry.
What makes the MK25 stand out is its no-compromise build quality. The stainless steel slide wears a durable Nitron finish, the alloy frame is hard-coat anodized for protection, and the carbon steel barrel is built to last. The double-action/single-action trigger gives you control when you need it, while SIGLITE night sights keep you on target in low light. An integral M1913 rail lets you mount lights, lasers, or other accessories—real modularity for a working gun.
At 34 ounces and 7.7 inches overall, the P226 MK25 sits solidly in your hand without being unwieldy. The 1.5-inch width and polymer grip make it manageable for extended shooting sessions. You get three 10-round magazines in the box—solid capacity for a full-size 9mm, and MA-compliant so it's legal where you carry. This is a pistol that respects its history while delivering modern reliability.
