I have the 5.5 in. 45 version. Its throat dimensions were off with both cylinders (.450), but that problem is easily rectified by sending them off to cylindersmith.com. If you don't shoot cast much, that may not matter that much. With cast, however, it helps to have proper throat dimensions. I use the 45ACP cylinder for inside shooting during winter months, and the 45 COLT for hunting and plinking in the Summer. The 45 Colt in the blackhawk can be loaded to 44 mag potential, and with this ability, makes this a very usable gun. I've had mine only 9 months or so and find that I shoot it more than all other guns combined. The Ruger can be a bit rough, but with a poor mans trigger job (easily done by you), and opening of the throats, you have an excellent shooter. Cheap leather is available, although I wouldn't use it for concealed carry. The shorter barrel would also be tempting.
