I recently saw a .22 pistol at the local gun store that I thought was interesting. it was an older one, an H&R if I remember right,
it LOOKED like a single action, (Think Heritage arms or Ruger single six ) The main complaint about Single actions for practical use is the slow reloads, this one had a tip out 9 shot cylinder, and it was actually DOUBLE action.
Combined the "Classic" Old west styling with all the improvements of the modern revolver.
