I finally got around to taking my shotgun to the range today to give it an airing out. First five rounds went fine. Reloaded and went for a second run. After I fired the first round the pump just wouldn't cycle. The action lock lever was stuck about halfway in and wouldn't move. So obviously the forearm wouldn't move. I tried everything I could think of, short of taking it by the barrel and smacking it on the ground (It did cross my mind). When I got it home i removed the barrel and tried again, It broke free and finally expended the empty shot shell. I have broken it all the way down, cleaned and oiled, and the action works as well as it always has. This is the only problem I have experienced. Anyone else have this problem? Insight?
