I have a G21SF and G30SF with the stock plastic sights. I can get the Truglo Tritiums installed for $55.00 + tax each or send the slides to Glock to install their night sights for about the same or maybe a little more money. Since I don't have a Glock with the factory night sights with which to compare to the Truglo, can someone with experience with both give me some guidance on which will be the better sights? This is about all of the money I can spare for new sights right now. Maybe I can upgrade to the fiber optics at some future date. Thanks for any advice or guidance.
