I read and research **** to death before doing things so I knew it could be an issue so I also heated mine prior to trying to loosen it. Still ended up in this mess. Probably more of an issue with a poor tolerance wrench.

I've done 2 other shields where the screw came right out. This one must have been extra loaded with locktite. Per S&W it's only supposed to be a very small dab.

With a dremel I wold have to damage the sight which I'm fine with. Although it would still be a reach that it would work.
