Everyone is talking from rumors and here-say
I have the Benelli M4 and this shot gun has never once jammed, no matter what round, what grain or what size I've put through the barrel
I've brought it to the range and put hundreds of rounds through it day after day
Ask Ryan (Dr. Moab) on this forum about it. While with him and his family in the San Rafael Swell, his brothers, who are police officers spent over an hour putting my shot gun through the paces and all were drooling over how amazing it shot.
No matter who shoots this gun leaves with one intention, going straight to a store to put some money down to get one of their own
I'd find a range that allows rentals and check it out for yourself, but I cant say one bad thing about this. My daughter even can shoot 3" magnums through it all day long and she's a very small framed girl
