One more comment.
I just read, I think in the Daily Mail, that Baldwin said the accident happened when he was practicing his cross draw.
That is very odd because it really is not normal to cock the hammer and pull the trigger when practicing the draw.
If you are dry firing, drawing and dry firing in one motion makes sense. Odd to me that one would be practicing the draw under the circumstances. Safety demands that dry firing be practiced in a safe area with no one in the immediate area.
He is digging his hole deeper. His lawyer needs to put a muzzle on him.
Duct tape might be better.
The SAA requires the hammer to be pulled back manually, it’s a separate action from pulling the trigger.
If the trigger is pulled before the hammer comes back, the hammer won’t lock. That is how “fanning” a single action is done.
