Great concept - flimsy solution - TruGlo Brite-Site Tritium Fiber Optic TFO Handgun Night Sights, Green Front & Rear

Installed the sight without any specialist tools, aligned it and locked all screws with thread locking agent.
But after around 500 shots the front sight became loose!
The problem is that one - just one - very thin screw is holding a very elongated front sight and there is simply too much torque and stress on that point as the gun is shot(the sight is elongated due to fiber insert).
Had to re-install it TWICE using metal based epoxy until it finally seemed to be fixed permanently. Simply re-tightening and re-locking the screw did not do any good.

Great concept, but very poor solution. The front sight opening in the slide is simply not designed for such sights.
Pros: Works as advertised, both night and day
Cons: very flimsy front sight
