Overview
Glock U64550203 45 Gen 6 9mm 4.02" Optics-Ready Pistol, 17-Round, 3 Mags
The Glock 45 Gen 6 U64550203 is a full-size 9mm striker-fired pistol built around a 4.02-inch barrel, optics-ready slide, DLC finish, 17-round capacity, and three included magazines. The G45 format combines a full-size grip with the shorter slide and barrel length associated with the Glock 19 pattern, giving the pistol a different balance and handling profile than a traditional full-length service pistol.
The defining feature of this exact configuration is the Gen 6 optics-ready setup. It retains the full-size 17-round grip format while adding a factory optics interface, fixed sights, and the updated Gen 6 platform features specified for this model.
For buyers comparing Glock service-size 9mm pistols, the 45 Gen 6 sits between the proportions of the Glock 17 and Glock 19 rather than following either format exactly.
Full-Size Grip with 4.02-Inch Barrel
The Glock 45 uses a full-size frame with a 4.02-inch barrel. That combination gives the pistol the magazine capacity and grip length of a full-size platform while keeping the slide assembly shorter than a Glock 17-length configuration.
The shorter upper changes the overall balance and sight radius while preserving the larger grip surface and 17-round magazine format.
Gen 6 Optics-Ready System
This model is equipped with Glock's factory optics-ready system, allowing compatible red-dot sights to be mounted without aftermarket slide machining.
The optics-ready configuration gives the pistol a factory-supported path to electronic sighting while retaining fixed iron sights for conventional use.
Striker-Fired Operating System
The Glock 45 Gen 6 uses Glock's striker-fired semi-automatic action and polymer-frame construction.
The operating system keeps the external control layout simple and consistent with the broader Glock pistol family, making the Gen 6 updates part of an already familiar mechanical format.
DLC Finish
The slide uses a DLC finish specified for this model. The dark surface treatment provides the external finish for the pistol while maintaining the low-profile appearance expected from a service-oriented Glock configuration.
17-Round Capacity
The full-size frame uses 17-round magazines, giving the G45 the same magazine-capacity class as Glock's larger 9mm service pistols.
This exact package includes three magazines, which is part of the factory configuration for U64550203.
Fixed Sights
The pistol is supplied with fixed sights in addition to the optics-ready slide. This allows the firearm to be used in a conventional iron-sight configuration when no optic is installed.

The Glock 45 Gen 6 Configuration
The Glock 45 is defined by its hybrid proportions: a full-size grip paired with a shorter 4.02-inch slide and barrel assembly. That gives it a different handling profile than either a full-length Glock 17 or a compact Glock 19 while retaining a 17-round magazine format.
In this Gen 6 configuration, the factory optics-ready system, DLC finish, fixed sights, and three-magazine package complete the setup. The result is a full-size-capacity 9mm pistol built around a shorter upper and a factory-ready optics interface.
