Yes, but wouldn't you agree that you shouldn't have to do that in the first place? I'd have a hard time living with that myself.
1911's are definitely for people who like tinkering with their guns. If you want a gun that is guaranteed to go bang right out of the box every time, buy a Glock, XDm, M&P, etc. I kind of like working on my guns a bit. That being said, my EDC is a Kahr!!
