Tom, I have a Blackhawk in .44 mag I bought a couple of years ago and have the same issue with the front site. It's too short, and of course on the blued models you can't replace them. I solved the problem by grinding down the rear site until there's barely a notch left to site through. I haven't tried anything heavier than a 240 grn bullet but there's no use.
Would it really be hard for Ruger to figure this out?
