The G34 Gen5 MOS configuration provides a long sight radius and the 5.31-inch Glock Marksman Barrel for enhanced precision. The slide features both front and rear serrations for confident manipulation, an nDLC black finish, and a MOS cut with the cover plate installed. This example retains the solid top slide design without the earlier lightening cut.
Gen5 updates are present throughout: ambidextrous slide stop levers, a flared magwell for smooth reloads, and the Gen5 grip texture with no finger grooves. The pistol uses Glock's Safe Action system and a striker-fired, locked-breech action. The frame is black polymer with an accessory rail for compatible lights or lasers.
Sight regulation is handled by a Glock polymer adjustable rear sight paired with a polymer front post with a white dot. The left-side magazine release is easily reached, and the setup ships with two 17-round magazines plus one 33-round extended magazine for added capacity options.
Markings indicate "Made in Austria – Glock, Inc., Smyrna, GA." The slide, barrel, and frame share matching serial numbers, an appealing detail for buyers who value complete, factory-matched components.
