Mossberg 590 problems

[Gunga Din]

Just purchased a new 590 and does not seem to feed properly when I pump then the action during rapid or slow fire sometimes it misses a round and the it falls out the bottom. Im not short stroking the weapon and I have used all types of ammo It just seems to me maybe the action is out of wack or something, but it does not happen all the time. Just wondering if there is a quick fix or if I should send it back to Mossberg.
Thanks in advance

If you are sure that you aren't short stroking then I would send it back. It could be something in the mag causing it or your shell stop could be bent a little. I'd send it back. George
