Thank you very much for the reply, I have since found that the mag for the Mossberg 715 T will fit fine as to why the 10 round clips don’t work, It’s just a pain in the neck to reload every other minute, also Like to add, my brother has the same gun that I do, but he is in Louisiana and I am in the Communist state of New Jersey, so I have no choice but to stick with the 10 round clips thanks again, sir. Have a great day.
