Have you ever seen a professional, sponsored trap shooter? Man, they are fast. With a bead no less...no fancy aimpoints or eotechs. If a bead and a rib are good enough for them, they're good enough for me. I could see the desire behind an ultra-fancy, $24 tritium bead on the front. A bead is very fast, natural and there is zero lbs of added weight.
I have an 870 marine magnum that I bought the second year they were available. That's about as tacticool as I get. I don't even have a slip on ammo carrier on the butt.
In all my years of shooting skeet, I've never needed a heat shield. We're talking shooting 100's of rounds through pumps or auto-loaders and the barrel gets a little hot, but not enough to scald you.
I admit that I do like lights added to the front, but I prefer not to use the business end of my shotgun to identify an unknown entity...especially since I have a pubescent child that sleepwalks.
To each his own, though! If someone wants to build an all out tacticool rig, so be it!
