A SIG-Sauer, apparently a P226, with a bolt-on compensator and adjustable rear sight. The SIG Sauer is barely readable in the photo. I cannot talk myself into seeing the SIGARMS INC Herndon-VA that appears on the slide of my P226, and wonder if the pistol began life as a German domestic sale.
Edit to add: Arrrrgggghhh!!! Check the Sigarms site? Who? Me? I have the P226 within reach! Don't need no stinkin' website! Judging by the placement of the front sight on the comp, it does indeed appear to be the 220 Sport. Still curious about the roll mark, though.
