It seems one needs to spends quite a few dollars to get a 1911 these days that isn't a plain jam o matic or at best something you can't trust your life to.

Obviously 1911s of the 1940s were mass produced side arms without the custom fitting most good 1911s get today.

Did they work well? If so, how? Was it the lack of hollow point ammo?

What about in mud and dirt?
