The Glock 22 Gen 5 MOS in .40 S&W has quickly become one of my favorites for several reasons. First off, it’s just classic Glock reliability, but with all the Gen 5 upgrades that make a solid gun even better. The lack of finger grooves gives the grip a much more comfortable, natural feel, and the aggressive texturing on the front and backstraps really locks it in your hand, which is especially helpful with the snappier .40 S&W round. Recoil management is surprisingly good, thanks to the dual recoil spring, definitely feels smoother than older Glocks I’ve shot. The MOS feature is great for adding an optic, which was a game-changer for me in terms of faster target acquisition. The ambidextrous slide release is another nice touch, making it versatile for both lefties and righties. The trigger is typical Glock, clean break and crisp reset, but the Gen 5’s version feels a bit more refined. Overall, the Glock 22 Gen 5 MOS hits that sweet spot for me: dependable, well-balanced, and easy to shoot. Whether it's for the range or home defense, it does the job well.
