mossberg finally got back to me. what a class operation[:@] NOT! they first of all wanted to charge me 80$ to replace slide parts AND SAID WE WILL GET BACK TO YOU. then i asked them to guarantee me that this would fix the problem. they tested the gun after new parts and said it still ejected the heavy ammo the same and said that they posted on there web site that with high brass or heavy loads to expect the action to fly open. this wasnt in my owners manual! i smell something funny( class action lawsuit). i told them if the gun is still doing the same thing why put the new parts on and charge me 80$. i told them to put the old parts back on and ship it back. i guess i will have to stick with bird shot and buy me a benelli. this will be my last mossberg!!!!![:@] i have delt with WINCHESTER, RUGER AND THOMPSON CENTER IN THE PAST AND THEY ARE THE ONLY TRUELY STAND BEHIND COMPANIES I HAVE DELT WITH!!!!. i always thought of mossberg as the gun for the average guy but after this i will spend my gun money elsewhere!
