I just got an 18inch 870 w/ factory +2 mag extension (no dremmle tool bs). So the factory follower (high vis) is getting caught up in the mag tube at the spot where it transitions into the mag extension. Sometimes during loading, preventing me from loading round 5. And sometimes during cycle where rouds 1 and 2 cycle normaly, then the folower gets stuck and the remaining 4 shells just slide around in the tube b/c there is no spring pressure. This is really pissing me off, everyone talks about the reliability of the 870, and here i have one thats all stock, that i cant trust for HD. I dont know if the follower is to blame or the mag extension. Anyone have any experiance with this?
