Need some help - when u disassemble the gun ( gun is new ) and reassemble- it will unload properly and release 2 shells in mag tube- however, after u shoot the gun several times, and want to unload it, when u push release button under trigger, it will not drop the 2 shells in mag tube ? I have 4 Benellis and this is the only one that has this issue- I did send gun to Rob roberts to have a slammer button installed - so I’m wondering if something is out of alignment or carrier latch is out of adjustment?? Any help
