I have a couple of handguns with rear sights that are part of the frame. One is an inexpensive Heritage 22/22mag revolver which actually shoots great groups. The other is a brand new Taurus Judge with the longer barrel. The 22 shoots about a foot to the left at 25 yards. The windage of the Judge is off to the right (I am not as bothered by elevation, both shoot high). I HATE this! I swore I would never buy another gun with basically no sight adjustment again, but the Judge has been hard 2 get here and I got a decent deal. Plus I am the ultimate "gun whore" and can't seem to help myself. I have learned that by widening the rear notch, I can move my windage. Can anyone tell me about how much of this "widening" it would take to move a foot at 25yds? If point of imp. is left, I should remove a small amount of the right "ear" correct?
