They are great sights, but please be aware that whether or not they will be good for long range accuracy will be dependent on the shooter as much as the firearm/sights. Many target shooters prefer fiber optic sights with very thin fiber optic rods and some even prefer things like blacked out rear sights with thin front sights. Some shooters also prefer having adjustable target sights so they can accurately adjust the rear sight for windage and elevation. There are hundreds of options for Glock models, but knowing what is going to be best for you will depend on you as an individual.
