Calling any BOGS who have pretty lousy vision,like me. I am having difficulty seeing the top of the front site on my SW 686+. Therefore some of my shots are high, some low, as I can't sharply align it with the top of the backsight. The front sight has some orange thing on top. Probably supposed to be very visible, but for me it isn't. Anybody know where these S&W front-site inserts are available locally? If none, I'll probably just paint that orange thing with flourescent paint (what's the best locally-available flourescent paint?) Thanks. Its a great gun, that orange thing just isn't very visible - not in gunrange light, anyway.
