I have been thru alot of sights for my glock 19. Heinies, Meprolights, Novaks, you name it. On a whim I ordered a set of the Amerglo Pro Glo with the serrated rear. Service was great, shipped fast. I paint all my front sights anyway, so I got these out of laziness on my part to stop having to touch up other sights. Put them on my glock 19, went to the range at work, put about 200 rds thru them various drills and distances. For me they are spot on. The orange really makes them stand out. For me and my money Ameriglo is a great company to order from. Waiting on my second set for my other Glock 19 so I can have it set up exactly like the first one. Anyone looking for a good sight that catches your eye may want to look at these. For me they work out great.
