I believe it was Wyatt Earp who said “Speed is fine, accuracy is Final…”. Bottom line,no matter the power or quantity of ammo, if you can’t hit accurately ALL the time with it, it’s not doing you much good. Find a weapon/caliber you can shoot, then practice, practice, and practice some more. Marksmanship is a perishable still. If you don’t work to maintain it you WILL lose it. The guy that shoots 50 rds once a year is NOT the same as the guy who shoots 100/week. The latter will be far more effective even if his is a .22 than the .45 shot annually. I like a .32, and I’d buy a J frame in .327 if I could find one. I’d also reload for it and shoot it a lot. The ammo issue alone would make this tough, and prohibitively expensive,if you don’t roll your own.
