The Glock 34 Gen 5 MOS is a full-size, competition-ready 9mm pistol designed for precision, speed, and reliability. With its extended 5.31” Glock Marksman Barrel (GMB), the G34 offers superior accuracy, enhanced by an improved barrel crown and advanced rifling.

As part of Glock’s 5th Generation series, this model features a flared magwell for faster reloads, an ambidextrous slide stop, and a reversible magazine release—making it well-suited for both right- and left-handed shooters. The removal of finger grooves and the modular backstrap system provide a comfortable, customizable grip for all hand sizes.

The Modular Optic System (MOS) allows easy mounting of red dot sights without the need for custom slide milling. Note: No blank MOS plate is included with this listing. The nDLC slide finish offers increased corrosion and wear resistance, making this an ideal firearm for competition, duty use, or personal defense.

This listing includes two 17-round magazines and one 19-round magazine (17+2 base plate), along with the original Glock case. The pistol is pictured with an FDE RMR and X300U-A, both available separately.
