I'm hoping someone may have one laying around, or on a revolver they would like to change out. I would like to have the hole already drilled out so I don't have to "mess up another one". I rec'd a new one from Smith the other day, and when I went to drill the hole for the roll pin, my Dremel wandered a bit forward. I figgered "no problem".....WRONG . When I fired the revolver yesterday, the rear of the front sight popped up about 1/4". Not good! I still fired a decent group, but I had the push the front sight back down in it's slot before each shot.
