If you simply MUST have a semi auto, I’d recommend something that was double action...no “cocked and locked” mess. Something that you don’t ever even need to turn the safety on or off. Grab the gun, pull the trigger and it goes “bang”. No fumbling around with safeties. (I absolutely detest them). Beyond that, I couldn’t recommend a specific gun. Try out a bunch and see what fits your hand best and which one works best for you.
Of course just for my own opinion, I’d say buy a nice used S&W model 10....
You’re just about dangerous.
