Well thigs were happening over the last year and I didn't get around to having the gun fixed until recently. So I take it to a smith and he shows me exactly what was going on with the jam issue. When you pump the forend backwards it wasn't mating well with the cam on the action bar, so the latch gets replaced. So I'm thinking great it's gonna work now and he didn't charge me too much either.......double good. Had it out 2 days ago and guess what it jammed again only this time I WAS able to press the latch and the shell popped out without having to tear down the gun. This is totally F*%@!# up and I'm scratching my head. I like the fit and finish of the 870, I just want something that will be reliable. Anyone have any insight to this??
