OK, how screwed am I? I wanted to install night sights on my G19. I watched all the "how to" videos and read all the related websites. Seemed simple enough, after all I can change a tire on my car with no problem. So I ordered a set of Trijicons, a brass punch and some Loctite 271. Did the rear sight first, no problems. I've actually done it before many times on other handguns. Prior to removing the front sight I made sure my 3/16 socket matched the front sight nut and it fit perfectly. So I removed the front sight, it was on there pretty good but I twisted it off with a vice. I inserted the front blade sight, added a couple drops of loctite and EVENTUALLY got the threaded screw going into the front sight blade. Now I know why other countries use small children for this kind of work, trying to get that lined up with my adult fingers was a major pain. And then I started turning the nut with the 3/16 socket and everything was going fine until....my socket lost contact with the hex nut head. But it was still far from being securely tightened. I was able to get it an extra turn or two with some needlenose pliers but this clearly wasn't the correct tool for the job either. And nothing else in my toll box that can fit inside the slide will grab that flat hex screw and turn it the rest of the way. So it's still pretty loose and the loctite is setting up. Now what? I'm hoping there is a way to "un-loctite" this thing as I really don't want to have to purchase another front night sight (not even sure Trijicon sells them that way) in addition to likely paying to have a professional do it correctly. And if I am really screwed, who is the best to send it to for sight installation? Thanks. Wanna kill these ads? We can help!
