For those of you who have a 45/410 barrel, I'd like to know what the height of the rear sight blade is. I measured mine from the flat of the sight base to the top of the sight blade and get .160 which is identical to the sight on the 357 octagon barrel. Now I know I'm not the best shot, but I couldn't even hit the paper at 25 yards! I was shooting someone else's reloads but that's another 'issue'. The previous owner of this barrel mentioned that there was some problem with the sights but didn't get into specifics.
