Just bought my first 1911-A1 style, the Springfield GI Series. What is the secret of getting the takedown pin back in without using something to depress the small spring pin? The book only says reverse the procedure for disassembly for assembly. The pin comes out easily to take the slide off, but is a real pain to get back in. I have scratched the frame and slide slightly trying to get it in without depressing the pin. Help! :cry:
