I just bought a used PT-99AF at a local gun show. The gun had minor rust flecking on the slide, which I have cleaned up. However, the rear sight will not adjust for windage (elevation adjustment is okay). The windage screw will turn, but the sight blade does not move. It appears that the previous owner locktited or glued (!!) either the rear sight screw or sight blade.
I tried unscrewing the windage screw and moving the sight blade - no luck. When the screw is backed out, there is a tiny spring visible. Are there any other parts hidden in there? How much trouble would it be to replace the internal parts and what parts will I need? Can thi be done without totally removing the rear sight from the slide? Thanks for any help.
