OK 1911/SA gurus, I have a Springfield Armory MilSpec that I'd like to get trigger work and night sights on. I believe that I've read that night sights on this pistol might be an issue due to dovetail size? So my question is would I come out better getting this weapon worked on or trade up to something already worked. The end result that I'm after is a decent shooter with night sights, nothing more.
