The way I see it, it's just something else that could malfunction during a certain situation and either get in the way of you running the firearm properly. When I had my 870 I would shoot 50+ shells at a time and not get burned, no heat shield on it. I thank all of you and your input on the versatility of the heat shield. I might keep my hands on it since no one wants to purchase it anyway. Have had it on here for sale for like a couple of days, just one slight interest but wasn't sure it would fit his thick walled barrel.
