I don't have any suggestions to your sight issue. The S&W pistols I have some trigger time with, with factory adjustable sights, seemed to be acceptable to me.
I'm curious as to how your pistol has held up over the years? I'm considering adding a 1006 to the stable as I have found a lightly used example at a reasonable price. Do you shoot "real" 10mm rounds through it? I ask that as most garden variety 10mm ammo is little more than top end .40 S&W.
I have a bit of experience with the round in the 1911 and a revolver, but I've never know anyone who has put lots of full power rounds through a S&W.
