First time on this Forum. Just picked up my BSN Tac. What I wanted to know before I go out and shoot this shotgun is the following: I loaded 4 rounds in the chamber. To cycle and test the action, I found that I had to unlock the slide each time a emptied a round. When I review videos on the web, it appears that each time the shotgun is fired, one cycles the round without the slide locking. Is mine locking up on each pump because I am not firing the shotgun? Thanks for your helping me understand what is going on.
