Can you explain what you mean by "tinkering" with your 1911?
You can push the safety out with your finger on a 1911 and it is not difficult to do. Just put it back in if this is what you did. And make sure the retention/slide catch spring didn't fly out of it.
The only hard pin that is on a 1911 is the grip hammer housing/lanyard/magwell part. Also depending on if you have a series 70/80, there might be some more pins but on a series 70, it's pretty easy to get all the pins out with your hand. It's almost like a glock, where you can break down the entire gun ridiculously simple.
Otherwise if it is indeed broken, then unfortunately it is not a drop in part. Getting the same one might fit but chances are you might have to do minor fitting. Fitting is not terribly hard for the safety.
