Glock has started expanding through its lineup, combining the best benefits of the slide cuts for MOS, with the overhaul of the Gen 5s – an outstanding pairing. I would have gladly upgraded, but did not want to abandon the Trijicon RMR Type II I’ve become so fond of. Just in mag changes alone I noticed a significant difference in the time required, the ease of use, and the solidity of the mag seat. I carry a Gen 4 G17 MOS on duty and when the Gen 5 came out I really admired the sleek new finish, the smoother trigger and, most of all, the flared magwell. Finally, magazines were equipped with orange followers allowing shooters to see an empty chamber or quick identifier for how many rounds were left. The muzzles on the Gen 5s were also rounded to aid with reentry to holsters. While this is not a selling point for me, it makes sense to a head of an agency that might have to buy a few thousand guns trying to outfit an entire department with a percentage of left-handed shooters. The finger grooves from the Gen 4s disappeared and the guns also became truly ambidextrous.

This is huge to some Glock fans as a whole aftermarket has developed to support this option for those who like to press check or even load and reload using the front serrations. New to the Gen 5 MOS are forward slide serrations. The flared magwell, improved trigger, Glock Marksmen Barrel and tougher nDLC finish were the primary upgrades seen with the new iteration, though other advancements came along. Essentially, Gen 5 meant a slew of upgrades that were largely evidenced from the aftermarket and customer demand.

Now, the Gen 5 version has emerged combining the best of both worlds. Quite a few companies have rushed to fill the market with quality micro red dot optics suited for this platform. Shooters could take advantage of the red dot optics that are growing in popularity. With Gen 4, Glock added the MOS or Modular Optic System option. 5 underused ways to improve police firearms training
