I just purchased a used P-3AT second generation. I field stripped the gun and did a little fluff & buff work on it, and cleaned it up well. I was able to remove the extractor and firing pin and spring and clean those up as well. What I cannot seem to figure out is the proper size hex to use to remove the belt clip. I want to remove it so that I can rebend it to make it tight again. I may decide to remove it altogether if it won't fit into a pocket holster with the clip on. Thanks in advance for any help.
