I just got a new shotgun (new to me, but it is well worn), it is an Ithaca model 37. After you fire, you cant cycle the pump back to get to the next round. You can pump it freely, cycle shells through it freely (as long as you dont fire them), and you can dry fire it and cycle the action like there was a round in there. You can also insert several snap caps and run them through flawlessly. I took it apart and cleaned and oiled the gun. Nothing is loose in the gun, the pump and the slide are both very solid feeling. Any thoughts???
