Blackhawk
I like both but don't have a Single Ten so I'd go for it.
Semi's can be fussy about ammo,and certainly won't function with cb's or shorts.The revolver won't care what you put in it.I have Mkiii's topped with optics.
SGW worked this one over for me, it visited his massage parlor, and added the parts. I really like this pistol.
