Product Overview

The Glock 45 Gen 6 MOS 9mm represents a refined evolution in one of the most trusted handgun platforms available. This model is a “crossover” pistol, skillfully blending a full-size grip frame with a compact slide length. The result is a 9mm handgun with a 4.02-inch barrel and an overall length of 7.44 inches, offering an exceptional balance of shootability, control, and concealment. It is engineered for serious users, including law enforcement officers, qualified civilians seeking a dependable home defense firearm, and dedicated competitors in practical shooting sports. Its primary uses are centered on duty, defensive applications, and intensive training, where reliability and adaptability are non-negotiable.

Key Features

Gen6 MOS Optic-Ready System: The Modular Optic System (MOS) slide is precision-milled from the factory to accept a wide array of popular micro red dot sights. This allows for rapid target acquisition and enhanced accuracy without the need for aftermarket slide machining.
17+1 Round Capacity: Utilizing a full-size magazine, the Glock 45 provides a substantial ammunition capacity of 17 rounds in the magazine plus one in the chamber. This offers a significant tactical advantage in both defensive scenarios and extended range sessions.
Crossover Frame Design: This design philosophy pairs a compact slide (G19 size) with a full-size frame (G17 size). The full polymer grip accommodates a full firing hand purchase for superior control, while the shorter slide reduces weight up front and improves holstering characteristics.
Enhanced Frame & Interchangeable Backstraps: The polymer frame features the latest Gen6 texture for a secure grip in all conditions. It includes multiple interchangeable backstraps (beavertails and non-beavertails) to customize the grip circumference and angle for a perfect, personalized fit.
Glock Marksman Barrel (GMB): The 4.02-inch cold-hammer-forged barrel features enhanced polygonal rifling and an improved crown for increased accuracy and consistent performance with a wide variety of 9mm ammunition.
Dependable Fixed Sights: The pistol comes equipped with sturdy, polymer fixed sights that provide a clear sight picture. They are designed to co-witness with most micro red dot sights mounted on the MOS platform, ensuring a backup aiming system.

Performance & Applications

The Glock 45 Gen 6 MOS is built to excel in specific, demanding roles. Its design directly addresses the needs of users who require a versatile tool capable of performing across multiple disciplines.

Duty & Defensive Carry: For law enforcement or qualified civilians carrying under permit, the crossover design is a significant advantage. The full-size grip provides maximum control during rapid fire and one-handed manipulations, while the compact slide makes for a more comfortable all-day carry, whether in an open-duty holster or a concealed carry setup. The high capacity and optic-ready capability make it a thoroughly modern service pistol.

Home Defense: As a dedicated home defense firearm, its legendary Glock reliability is paramount. The 9mm chambering offers effective stopping power with manageable recoil, crucial for high-stress situations. The ability to mount a weapon-mounted light to the rail and a red dot to the MOS slide creates a highly capable system for low-light identification and rapid, accurate shot placement.

Training & Competition: The balance and shootability of the Glock 45 make it an outstanding platform for high-volume training. The reduced muzzle flip of the compact slide allows for faster follow-up shots, while the full grip aids in recoil management. In divisions that allow red dots, the MOS-ready slide makes this pistol a ready contender for USPSA Carry Optics or similar practical shooting competitions.
