G21 front sight won't come out

I have a used G21.3 that I believe is out of a law enforcement armory. The original sights have been replaced with Trijicon H3 06 sights which have lost their glow, so I want to replace them with Truglos. Here's the problem: I can't get the front sight loose. Strangely, the little hex head screw that's supposed to hold the sight on was missing. I have tried to punch the sight out, even with significant heat applied, and the sight won't budge, even a little. It bent my punch, but wouldn't move. I've performed this operation on other Glocks with no problem, but this has me stymied. Any ideas?

I've never seen anything like that... As long as the original installers didn't grind on the slotted hole, you should be able to install your new sights.
