S&W K22
I know it's not on your list, but the only way to learn a skill such as double action shooting is with a good double action. They can be both deadly accurate and fast and fun.
My first pistols were a single six and a Mark I, truth be told I would have been better served with a K-22, 17, 18 or 617. I do have a 6" 617, and there are 10's of thousands of rounds that have gone down her barrel, but she is a bit heavier than need be.
The pick of the litter in my mind would be the 4" model 18 (I'm still looking for one of those).
