When my two daughters were very young, I bought each of them a brand new model 63-3 with 4" barrel and put them in the safe. One is 23 now, the other 20.
I taught each of them to shoot a handgun by starting them out with the model 63's. I can't tell you how excited they were when, after shooting the revolver for the first time, I told each of them that the gun was actually theirs!
It was a struggle coming up with the $360 for those pre-lock 63's when the kids were younger. Now I wish I had bought 10 of them (or at least ONE for myself too!)
My suggestion is to find each of them a pre-lock 4" model 63 or model 34. I believe that ANY pre-lock S&W revolver will continue to appreciate in value, even it you shoot it.
