Looked at a nice 4566 TSW today. There was a strange button on the underside of the trigger guard. The owner stated that it was a trigger lock. There was a tool that turned the button and deployed a block to obstruct the trigger being depressed. I own several Smiths, my Dept used Smith 3rd Gens in 9, 40, 45 but I have never seen such a trigger lock. I've searched the web and can't find reference to it either. The PDF owners manual for metal autos on the Smith & Wesson doesn't show it either. What gives?
