We've been talking on another thread about a project gun I'm hoping to build (longslide Glock in 9mm and .357sig). I'm also wondering about sights. I want the brightest, most noticeable possible sights fore and aft. I'm really certain that means fiber-optics. Thoughts on that? I *might* want to carry this gun sometimes during some times of the year, and might want to have it on the nightstand (more likely), so I've been considering TFO sights (tritium fiber-optic, where the tritium glow shines up through the fiber optic tube). Anyone have experience with these sights? I've heard raving reviews, and also heard that the fiber optic insert will pop out on some of them... I'm looking for the very awesomest sights, essentially, so if the TFOs do what they're supposed to, it might be them. One thing that's definitely a requisite for any sights for me: it really bugs me when there's a tritium insert/fiber optic mounted in a front sight with some metal over the top of the bright part. I'd really like the fiber optic part to be the very tip-top point of the sight (because that's the part I try to look at when I shoot), so I don't want a big metal plate over the top of the bright part. That rules out some brands of fiber-optics. Also, anyone have experience with these Goshen Hex-sites? I might consider trying it out - just seeing if I could turn in significantly better scores on IPSC courses with them. Anyone tried something like this? Thanks!
