I have been trying to find a new front sight for 3" gp 100. It is different than the 4" or 6" There is no easy release button on the 3". There is a pin holding it in place. I have looked everywhere on the internet for a new front sight for the 3" model and I can't find one? I looked everywhere on this forum as well hoping to find some answer, to no avail. All everyone talks about when it comes to replacing gp100 front sights are the easy to replace ones on the 4" and 6" models. Which I have the 6" model as well and have replaced that front sight with fiber optic. So if anyone could help with this I would deeply appreciate it. Treefrog out.
