That's a couple of fine looking revolvers you got there. I thought that top one was a Model 19-9 like the one I've got, but then I noticed the unshrouded ejector rod, and the tiny holes in the target. Obviously a 22. Still a nice gun. Maybe I'll have look for one like it.
The S/A is a Uberti? Look like Uberti grips anyway.
Good shooting with both.
