OK 1911 experts out there, I have some questions. While shooting the other day my safety stopped moving from "safe" to "fire" because this pin was getting in the way. This hasn't happened before. I can move the pin out of the way with my fingertip and disengage the safety, but there is obviously something wrong for it to be doing this. Safety off Safety on, you can see that the pin has come out of place and is blocking the safety. What do I do?
