Just as a note, I am David, Robert is my dad. Anyways, I just got my Springfield Armory Mil-Spec back from the gunsmith. Had a trigger job and Wilson Combat ambi safety installed. A good trigger job compliments the 1911 so well. And the ambi safety is very convienent, especially for my wrong-handed brother. The gunsmith had a pretty hard time getting the ambi safety apart so he could do the trigger job, but I would still like to know if there is any chance that it will "shoot loose". Do I ever have to worry about that?
