There is no substitute for practice. The cheaper the ammo, the more practice you'll get. For that, the .22 is the hands-down winner.
FWIW, all but one of the accidental handgun discharges I've been around were semi autos. I don't think a semi auto is the perfect first handgun. IMHO a DA revolver is much better.
