Hi, all:
870 DM owner here bought new from a local gun shop. I have a 6 and a 3 shot mag and the 6 shot works reliably as long as it's properly seated. The 3 shot only feeds with 2 or fewer shells. With 3 shells, the shell really has no give downward and jams the gun. with two there is plenty of give. I think it's the mag follower.
TLDR: Did somebody put the wrong follower in my 3 shot magazine? Should it be the exact same size as my 6 shot (it is)? Anyone have a 3 and a 6 to compare?
Thanks
