Well, I need to check the length of my sear pin, because I think that might be the root of my problems. I have my calipers all ready, but I can't get the sear out of the trigger frame. It's atached to the plunger, so it won't come out. Do I need to turn the nut that connects the sear to the plunger? If so, how far do I turn it back in after I take it out?
