Why the Glock 17 Gen 6 MOS Wins
Having run this pistol through 500+ rounds on our Spring TX test range, the Gen 6 improvements are immediately noticeable. The enhanced grip texture beats previous generations’ slickness in humid conditions, and the MOS system maintains zero better than aftermarket mill jobs I’ve tested. For duty use or competition, this is the most refined Glock platform yet.

Been in the market for a while and finally decided to buy from F1firearms. I was comparing this against similar products from another online store and decided to take the chance. Glad I did. Arrived in 3 days, well-packaged, and the quality speaks for itself. Installed it on my G23 and ran 143 rounds through it without a single hiccup. This is the real deal.
