There are some oddball exceptions, but usually revolvers don't have safety catches; to have an S&W revolver with a safety would show ignorance.
The S&W revolver you mentioned was my first pick all along (and it fits b/c as you said, it was a common piece). Since there's no safety, then either I'll have to pick another gun or just stay with my original scenario of a couple bad primers.
