I have a Springfield Armory 1911-A1 in 45 ACP that is giving me problems with the thumb safety locking in the On position.
Thinking that perhaps some grit has gotten into the spring-loaded plunger on the side of the frame, I am trying to remove the thumb safety to take apart the plunger tube for cleaning. Light tapping on the pin that the thumb safety pivots on doesn't seem to be producing any movement, so I am wondering if some part of the action has to be removed first to free that pin.
I don't mind being told that this is something better left to a competent gunsmith. On the other hand, I am somewhat mechanically inclined, and am not scared of learning as I go.
Can anyone help me out?
