I had a Millet front and rear sight put on my Series 70 Colt some time ago. This was a mistake in that the front sight is double-staked, but I did not realize that at the time. Now the rear sight has developed a cant which is not a major problem other than looking bad but is something I would like to fix. Millet sights are no longer available and I have been able to find no sight that will replace the Millet and retain the front sight. I have heard of people having one or both holes welded up and the slide refinished, but I don't want to do that unless there is no other option. I suppose if I found another rear sight that is lower, I might have the front sight milled down. Can the Millet rear sights be rebuilt or repaired? Are parts like pivot pin and elevation screw available anywhere? I think the base of the sight is level, but the top part is canted, possibly worn or a bent pivot pin. I don't know how it got that way because I never dropped or knowingly abused it. Maybe those sights are just really fragile and could be a reason why they are no longer made. Any meaningful advice will be appreciated. I am hoping someone has had this same problem and has arrived at a better option.
