It takes concerted effort to learn to shoot double action well. It also takes a lot of effort to shoot a snubbie well. When you combine the two, you really, really have to work at it to get pretty good.

Many years ago I decided that I would get to be decent at shooting a revolver double-action. It took a lot of dry firing (make sure that the gun is empty and point it in a safe direction). It took a lot of range time too. I'll never regret taking the time and making the effort to do so however.
