TFO Night Sight question

Consort · November 30, 2014, 06:35 AM

I recently installed a set of Tru Glo TFO night sights on my G19. The screw securing the front sight is tightened as much as it can be without the risk of either breaking or stripping it. The rear 2/3 of the sight blade does not make full contact with the slide surface. I've read the installation instructions twice and have done everything correctly. I am thinking I might have just received a warped set. Any thoughts? I watched a guy on Youtube (after my effort) installing TFOs on his G41; he experienced the same problem. No resolution in his case.

I had the same issue on an XD. I think their design is gap to avoid maring the slide top.

Mine came factory installed on a G21. There are no gaps anywhere. I can't slide a 3x5 card in.

You didn't mention how much of a gap you have.

Have you shot it? Is it on target?

I had the same sights installed on a glock 19. I think there was a slight gap on mine, but I just ignored it. Varying degrees of tolerances I guess

The gap (more of a bowing) is what I would term significant. I haven't attempted shooting it yet. It does have a tendency to snag when coming out of the holster, though. Local gunsmith suggested epoxy, but I don't want to do anything that might ruin the slide.
