I'm in the process of rebuilding a Gen 2 Glock 19 I recently received from Aim Surplus and one of the things I don't have tools to do is install night sights. I thought about bringing the slide to the show this weekend and wondered if anyone knows of a reputable vendor with a good price on sights and the capability to install them at the show. I realize I can have it done locally by someone, but since I'll be at the show anyway I thought I'd ask.
