Are you going to install the Williams Firesights yourself? I would love to change out my Str8 8s myself but I think I read that the factory sights are installed with a Locktite type substance and I cannot even get the Allen mounting screw to budge with my set of wrenches and don't want to break anything off. I would love the chance to change out my sights and save myself the cost and time of a smitty . . . .Do I just need to get a stronger A wrench and push??
