Good advise on changing out mounting screws to higher grade ones. I'm still using the ones that came with the guard. They appear to be of decent quality. They tightened up properly and are holding strong so far. I should run a box of 3" turkey loads thru it to really test them out. But I trust that they will be just fine. Actually after looking at it again I see that the smaller screws are high grade button head cap screws. The pistol grip screw and nut is hardware store looking, and I might change that out, but I doubt I need to. I think you guys are just having fun busting my chops!
