1911's are like women, when you get a good one, you better take good care of it or you will regret the day you got it when you need it most. Stick with the good ones and don't go looking for bargains or you will end up with a problem that will cost you a lot of money when you could have avoided it by getting a first rate one to begin with.
If yours works, don't mess with it and it will probably run forever, if it's trouble from day one, divorce it and move on, as it may never give you a moments peace, and take you for all you are willing to dump into it.
You may find you and your 1911 in a therapists office trying to find where you went wrong. Picking up a cheap 1911 is like meeting a girl in a bar, they all look good when you are in the mood, but you can wake up without your wallet before you know what happened.
