Glock 45 Gen 6 MOS 9mm 4.02″ Barrel 10-Rounds – 9mm

Product Overview

The Glock 45 Gen 6 MOS 9mm represents a refined evolution in one of Glock’s most popular crossover platforms. Designed for the serious user who demands versatility, this pistol combines the compact slide of a Glock 19 with the full-size frame of a Glock 17, creating an optimal balance of controllability, sight radius, and holster compatibility. Chambered in 9mm Luger with a 10-round capacity and a 4.02-inch barrel, the Gen 6 iteration incorporates the Modular Optic System (MOS) directly from the factory. This model is engineered for law enforcement professionals, qualified civilian defenders, and dedicated shooting sports enthusiasts seeking a duty-ready firearm that excels in training, home defense, and professional applications. Its design prioritizes reliable performance under diverse conditions.

Key Features

• Gen 6 MOS Platform: The slide comes milled from the factory with the Glock Modular Optic System (MOS), allowing for the direct mounting of a wide array of popular micro red dot sights without the need for aftermarket machining. This provides a significant advantage for rapid target acquisition.
• Crossover Frame Design: Features the compact slide (4.02-inch barrel) paired with the full-size frame. This offers the reduced mass for a smoother draw and the full grip surface for enhanced control and recoil management, accommodating all hand sizes.
• 10-Round Magazine: Configured to comply with state capacity regulations while maintaining the standard magazine well dimensions. The magazine ensures reliable feeding and is constructed with Glock’s durable, corrosion-resistant steel and polymer.
• Enhanced Frame & Interchangeable Backstraps: The polymer frame includes a textured grip for improved handling. It comes with multiple interchangeable backstraps, allowing the user to customize the grip circumference and feel to achieve a secure, personalized fit.
• GMB Barrel & Fixed Sights: Equipped with a precision-machined, 4.02-inch Glock Marksman Barrel (GMB) known for its consistent accuracy. The optic-ready slide is paired with high-visibility, polymer fixed sights that provide a co-witnessing solution when an optical sight is installed.
• Refined Surface Treatments: The Gen 6 series includes nDLC finish on the slide for extreme hardness and corrosion resistance, and a more durable, non-slip surface treatment on the frame for consistent performance in all environments.

Performance & Applications

Duty & Defensive Readiness: The Glock 45 Gen 6 MOS is built to meet the rigors of daily carry and defensive use. The 9mm chambering offers an effective balance of stopping power, manageable recoil, and ammunition availability. The full-size frame provides a stable shooting platform, while the optic-ready capability allows for the integration of a red dot sight, a proven advantage in low-light scenarios and for shooters of all experience levels. Its reliability with a wide range of ammunition makes it a trusted choice for primary or backup defensive roles.

Intensive Training & Skill Development: With its balanced ergonomics and soft-shooting characteristics, this pistol is an exceptional tool for high-round-count training sessions. The consistent trigger pull and minimal muzzle flip aid in developing fundamental marksmanship skills, rapid follow-up shots, and transition drills. The MOS system future-proofs the firearm, allowing trainers and students to seamlessly transition to modern red dot optics as their skills progress.

Competition in Practical Divisions: While not a specialized race gun, the Glock 45’s reliability, accuracy, and now, optics-ready capability, make it a formidable option in practical shooting sports like USPSA’s Carry Optics or IDPA’s relevant divisions. The platform’s durability and minimal maintenance requirements are significant benefits for competitors who prioritize a firearm that can withstand thousands of rounds while maintaining performance.
