When I put my SA back together after cleaning, I have some trouble getting the slide stop back in place. The plunger assembly keeps it from going back into place. For now I have been using the end of a q-tip with the 'fuzz' broke off to push the plunger back enough that I can get the slide stop back in. The guy I bought it from must of had the same problem because there is a nice scratch on the frame from the slide stop. Are they really supposed to be this hard to put back into place or can I do something to make it easier?
