Hello all, I need some advice. I am installing a 10-8 Performance rear sight on my Tisas 1911. After fitting it, it is almost ready to be installed completely (just waiting on the Loctite). However, when it is finished, the rear of the sight will stick out past the rear of the slide by 1.3mm. It's not much, but will be annoying. I assume the dovetail sight cut on the slide was not quite in the right spot. Anyways, how would you guys go about fixing this cosmetic detail? Take a file to it and then re-serrate the sight (and possibly the slide)? Thanks for the ideas. That's the only one I can come up with.
