If you have an 870 with an issue - go see the man ...what would you have to lose ?
I am honestly baffled, totally mystified, by the Remington hatred.
I'm getting a Mossberg next though just so I can say that I have both(and the finish is better and will hold up better here).
Then, there will be the Browning BPS, then the Ithaca (in 28 gauge for giggles), and it goes on forever from there..........
