|I purchased two sets for two of the Glocks I own. Strangely, one fit perfect out of pack other had to be finessed, filed, and brass drifted into place. I even switched them and problem followed so it was the sight. Not only that but sight pricing has been trending downward. You can find very good tritium and even tritium-fiber optic hybrid sights for not much more...I think these need to come down a little to be a 5 Star item.
Having said that, these are good in most applications and the addition of the set screw on the rear sight to lock it down is nice. Once on they aren't coming off and I like the green-red-green sight picture.
Definetly a buy...just wish they were $10-$15 bucks cheaper.|
