I carry a .45 nothing wrong with a 22 it's just I want something to hit them and stop them cold. And in a home I feel as if the 22 would carry through more walls because its such a smaller round and could cleanly punch through drywall
When ever I go to buy a 1911 I always check to see how tight it is. Check the barrel bushing and slide and then if you happy with that just polish all the contact points and it should be a good gun
