I had a Ruger Bisley Blackhawk in .45 Colt.
Gun was as tough, and as heavy as a boat anchor, which I always called it.
I shot many thousands of rounds out of it- it was the first gun I really started experimenting with loads in- and I was the second owner.
I bought a used .45 ACP cylinder and it dropped right in, but only shot a few rounds out of it.
I traded the gun to a friend of mine who was a "hot rodder" reloader. He sized down 300 and 405 grain .458 bullets to .452 and shot them through it with no ill effects. Somehow, I ended up back with it again, and traded it off after a few years again to a bear hunter that moved north.
As far as I know, it's likely still kill'n bears, even after being abused.
A feller can't own more than two dizzy buzzard guns at once, or he might be accused of being a collector of them.
I did hate the front sight on that gun (or any blackhawk for that matter)- needs a gold bead and V-notch rear for any good target work. As they come, the front sights can double as a pair of brass knuckles in a fight though.
