I'm in the market for a Sig P226. I can get one for a great price through the IOP program at Top Gun Supply. The 226 Combat and the MK25 seem to be the same pistol, except for the color. Am I correct in this? I can't justify an extra $100 for the Combat, when I can get the MK25 for $830. Also, if you have a MK25 or a 226 Combat, how do you like it?
