I prefer the 1911 with a .22 "upper". It gives you better capacity and I prefer auto pistols over revolvers. I would also think a 5" barrel would be a minimum for a .22.
The rimfire rough riders are definitely inexpensive but they don't seem as well made as othe wheel guns. I only know one guy who has one, but he likes it fine. Maybe I'm prejudiced against them solely because of the metal they're made with, I don't know.
I used to own one, they are paper weights for accuracy. In fact I have known three other people that have owned them. All junk. There might be a good one out there but I have not seen it.
