I love my 870 and I have had it forever. I have not had any issues with it whatsoever. I put the Knoxx Stock on it, surefire light and ghost ring sights. I love it, but evidently there has been some type of issue with the newer models.
We had this discussion at work this morning about customers carrying open. We decided to allow it, all of us employess are still required to keep it concealed. I didn't argue, at least we get to carry at work.
