I posted this in the Smith Work forum, not sure if it will get answered there. So, I cleaned up the full size 9mm, and reassembled the recoil spring and guide rod onto the barrel and slide. When I replaced the slide onto the frame, it came back like normal, but the barrel and guide rod still protrude @ 1/2 " past the end of the barrel, and the slide won't come forward. It seems as if the barrel is hung up, can't see anything though. Any Ideas ??
