Got to admit to "Old Guy Brain Fade." Tom Kelly works for Smith and Wesson, and is great to talk to. Can't remember the guy's name from Burris, but he is a blast. I think they found him wondering around Pike's Peak with an old Coke bottle he'd made into a scope. The guy never did quit laughing when I told him the glass in my Speed Dot 135 was rattling after three shots on the 500. He even asked me if Tom Kelly had told me it would work. When I told him that Tom had told me that is what he had used on his 500 in a Brown Bear hunt (I saw it televised and called Tom about the optic), he asked me if Tom told me how it fell apart after they got home. When I said no, he started to laugh rather hard and long and said that Tom always leaves that part out.
Short story long ... this is how I got a brand new, Burris full warrenty replacement, Speed Dot 135 on my .22 pistol.
