Taurus makes a couple of models, but Smith and Wesson makes the ones of choice. I have a Model 25-2, with a 5" barrel, that I have had for 30 years. I am waiting for paperwork to clear to pick up a 625JM, which is the 4" Model 625, heavy barrel. It is costing about $670. There are also some S&W Performance Center models, but they cost even more.
I also have several Ruger New Model Blackhawks, 5 1/2" barrel, stainless, .45 Colt with .45 ACP cylinders. I am shooting a lot more single action now, double action some, and auto very little. The NMBHs with generic .45 ACP ball are a lot of fun.
