A .22 revolver is usually a very heavy DA pull. If the recommendation is to practice SA only, then I concur. Otherwise a Browning Buckmark would be a better option. .22LR and single-action is all about teaching proper aiming, breathing, etc. I don't think a DA revolver does that.
For those of you choosing both a 4" .357 and a 1911 why? I mean let's face it, while both the 1911 and the 4" .357 have a plus' and minus' over the other they're both in the same ball park. Seem's kinda redundant.
