Well Bob I highly recommend shooting any pistol or revolver with 2 hands if you can. Two hand shooting is just about twice as good as one hand shooting.If you don't believe it look at videos of any pistol or revolver competitor. BUT you do need keep all your parts and pieces out of the path of the slide travel on a semi-auto pistol and away from the cylinder gap of any revolver.
You don't need a revolver with bad alignment to cause damage to your digits if placed by the cylinder gap. The hot high pressure gasses alone can do serious damage to your digits no lead shavings needed. But of course lead shavings would just add to the damage.
We practiced to shoot with one hand many times in competition, as there are scenario's calling for both strong hand and weak hand shooting. There may be times you are wounded for instance in a real gunfight and one side or the other put out of action.
You should practice both strong hand and weak hand shooting, but I am here to tell you, strong hand shooting sucks compared to proper two hands stances. And weak hand shooting REALLY REALLY sucks. compared to strong hand shooting.:laughing: Of course the more you practice of each the better you will do.
