Glock G34 GEN4 MOS – 9mm

Description

Product Overview

The Glock G34 GEN4 MOS represents a significant evolution in practical handgun design, merging the proven reliability of the Glock platform with modern optic-ready versatility. As a competition-ready variant of the renowned Gen4 series in 9mm, this model is engineered for shooters who demand enhanced sight radius and accuracy for dynamic shooting sports, tactical training, and duty use. The standout feature is its factory-installed Modular Optic System (MOS), which allows for the direct and secure mounting of micro red dot sights without the need for aftermarket slide milling. With its longer slide and barrel, the G34 GEN4 MOS offers a smoother recoil impulse and improved muzzle velocity, making it a top choice for USPSA, IDPA, and 3-Gun competitors, as well as discerning enthusiasts seeking a superior defensive tool.

Key Features

• MOS (Modular Optic System) Slide: The slide comes from the factory with a machined mounting platform and includes multiple adapter plates. This system enables a secure, low-profile fit for popular micro red dot sights like the Trijicon RMR and Burris FastFire, facilitating a seamless transition to optic-based shooting.
• Gen4 Enhancements: Features the Gen4’s customizable frame with multiple backstrap inserts (Large, Medium, Small, Beaver Tail) to fit a wide variety of hand sizes. It also includes the Gen4 dual recoil spring assembly for reduced felt recoil and the rough-textured frame surface for a superior grip.
• Competition-Optimized Dimensions: The extended 5.31-inch barrel and full-size slide provide a longer sight radius, increased accuracy potential, and improved gas efficiency for consistent 9mm performance. Despite its size, it maintains a manageable weight of approximately 3.5 pounds unloaded.
• Factory-Installed Trijicon Sights: Comes equipped with high-visibility, three-dot metal sights from Trijicon. These provide an excellent co-witnessing reference point when using a mounted red dot and serve as a reliable backup sighting system.
• Enhanced Trigger & Controls: The “target-style” trigger connector offers a slightly smoother press with a defined wall and reset, preferred by action shooters. All controls, including the reversible magazine catch, are designed for ambidextrous operation.
• High-Capacity & Reliable: Ships with standard 17-round magazines, showcasing the proven reliability of the Glock Safe Action system. Its design prioritizes consistent feeding, firing, and ejection under demanding conditions.

Performance & Applications

The GLOCK G34 GEN4 MOS is not a general-purpose sidearm; it is a purpose-built tool for specific disciplines where performance margins are measured in fractions of a second.

Action Shooting Sports: In USPSA’s Production or Carry Optics divisions, and IDPA’s Stock Service Pistol or Carry Optics categories, the G34 is a dominant platform. The longer slide aids in faster transitions between targets and mitigates muzzle rise, while the MOS system allows competitors to leverage the speed and precision of a red dot sight. The transition from iron sights to a red dot system, as noted by many top competitors, can significantly enhance both speed and accuracy on complex courses of fire.

Tactical Training & Advanced Defense: For serious students of defensive handgunnery and law enforcement officers permitted to use personally owned weapons, the G34 GEN4 MOS serves as an exceptional training tool. The optic-ready capability prepares shooters for the increasing adoption of red dots on duty weapons, and the pistol’s inherent accuracy provides excellent feedback during precision drills. Its reliability ensures it can handle high-round-count training sessions without compromise.
