...I've experienced more failures with my 1911's. ...Enough that it has made me a little uncomfortable.
What you need is a case of .45acp, several magazines, some targets and an afternoon to get to know your 1911's. If it needs to be tuned so that it will work, then get it tuned. If you want to carry a 1911, you need to shoot a 1911 as much as possible. If you want to carry a 1911 because other people do, get another hobby.
Guns are a bit like cars. When you buy one new, it comes with a warrany. If something isn't right, you can get it fixed by the manufacturer. If you buy one used and something isn't right, you have to spend a little money to make it right. If you don't like it, sell it and find something you like better.
