If you're going to shoot BP out of a Colt's SAA then it needs to be plated.
My Off Duty/carry guns are blued Colt's SAA but I shoot smokeless through'm. I wanta see if I hit anything.
That is a problem with black powder. I deer hunt with black powder and it definitely causes problems seeing if the deer is hit and which way it goes. Deadeye Dick
Theoretically you're supposed to be a good enough shot that he won't run at all.
