Learn about the SIG Sauer P226 MK 25 in this video by The Firearm Blog... "The SIG Sauer P226 Mark 25 handgun was adopted by Naval Special Warfare Command after an initial solicitation by NSWC Crane. The handgun was and is still in use by a number of Sailors within this contingent, however the actual SEALs have and still are issued the standard Sig P226, rather than the Mark 25. Note that the other Sig handgun in here is actually a P229, instead of a standard P226. However for comparison’s sake, the P229 served well."
