I have a PT1911 with the factory front sight (Heinie) which has their (proprietary?) dovetail and set screw. The front sight always loosens up after a range session. Not to where it is going to be thrown off the slide, but a decent wobble. I have tightened the site back on using blue loctite, when it failed again I went ahead with permanent Red loctite. Twice. I thought maybe the gun got hot enough to break down the loctite (450*..yea right..). Not planning to change the sight ever I decided to fix this problem forever and put a dab of JB-weld or marine-tex (I forgot which) on the sight and put it in place.
Got back from the range. It's loose. Again. Any other suggestions? I mean...come on, JB-Weld loosened up? I must have not put enough on or something this makes no sense.
