Before you bash a gun think about the ammo you're using. This is like saying that a car brand is awful because you keep getting tire blowouts. I've used single shots that constantly jam because the shells expand in the chamber...it's the shells, not the gun. I've had my 870 for year, my cousins and uncle have had one for years, my brother and dad for years...no problems that wouldn't happen in any other shotgun. Yeah, jamming occurs, but we can point it back to the specific shells we are using. When I have a jam, everyone else in my group complains if they are borrowing/using from the same box. Some shells expand and get stuck. It happens no matter the gun. Does it mean a .22 rifle is bad because I have duds in the bulk ammo packs but no duds with the more expensive .22 shells? Put the blame where it belongs, not on the gun.
