I had an old model Blackhawk in .30 Carbine. It shot very well, but as already mentioned, it was LOUD!
One of the problems was I had to beat the empty cases out of the chambers. Sometimes I actually had to remove the cylinder and knock them out with a hammer and punch.
But like every other Colt/Cowboy style single action I've ever owned, the back of the trigger guard beat the snot out of the knuckle of my middle finger. This style handgun just doesn't fit my hand.
So down the road it went.
