I have a Glock 30 with 'standard' sights. I'd like to get tritium (or tritium fiber optic) night sights. Looking at topglock.com I see too many choices -- Truglo, Ameriglo, Trijicon, etc. Also, front and rear, or front only, or... I also have another constraint, or at least a strong preference -- I want sights that I can install myself. If I have to buy a $60 installation tool, that's okay. I don't have someone I trust locally to work on my gun and I don't want to send it away. I don't have any experience w/sight installation, but am pretty fearless on mechanical matters. Finally, a question about installation. If the (rear?) sight can be laterally adjusted, how do I insure that I've properly positioned it, other than test firing the gun. Given my mediocre marksmanship, it might take a few years to get the position correct! Thanks for any advice you may be willing to offer.
