Glock G34 Gen5 Modular Optics System 9mm Luger 5.31 inch 17+1 Diamond Like Carbon Slide

The Glock G34 Gen5 MOS is a competition-ready 9mm Luger that brings the long-slide accuracy and durability serious shooters demand, featuring a 5.31" Glock Marksman Barrel with cold hammer-forged polygonal rifling and an improved crown for tighter groups, an nDLC-treated slide for corrosion and wear resistance, and a Modular Optics System (MOS) cut that lets you mount popular red dots for faster target acquisition at the line or in practical matches. With a 17+1 capacity and striker-fired Safe Action trigger, the G34 Gen5 MOS balances controllable recoil and crisp trigger reset for rapid strings of accurate fire; ambidextrous slide stop levers and interchangeable backstraps let right- or left-handed competitors index the pistol to their grip and draw. The longer slide and extended sight radius—paired with adjustable sight options—make this model a favored choice for IDPA, USPSA, and 3-Gun shooters who need consistency from stage to stage, while the 26.21 oz weight and 8.74" overall length keep muzzle flip manageable without sacrificing balance. As part of Glock's Gen5 lineup, it omits finger grooves, includes the proven firing pin and trigger block safeties, and requires FFL transfer for legal purchase.
