I have a couple of 1911's that are easily field stripped without the use of tools. Other than the Main Spring Housing Pin needing to be punched out they can be detail stripped easily too. My question is this; On reassembly I have yet to figure out how to put the thumb safety and slide stop back in without very carefully using a small screw driver to push the plunger detents in while pushing the levers in place. Am I missing something here? Is there a way of doing this without a tool? I haven't had a problem scratching or marring the frame but if there is a way of doing it without a tool I sure would like to know.
