Franchi affinity double feed

[Tiddiecity]

My franchi affinity 12 g 3.5 is double feeding shells. Fire a shot then 2 shells eject from the magazine locking the bolt back so it can’t feed. Only carrier latch I could find was for a benelli M2 and it did the same thing after installing it. No dealer close that works on it. Any info appreciated

Carrier Latch is out of spec, not enough face contact with shells in magazine.  Replace or open RMA and have it "Adjusted"
