Glock P64550201 G45 Gen 6 9mm 4.02" Pistol, 10-Round Magazines

Glock P64550201 G45 Gen 6 9mm 4.02" Pistol, 10-Round, 3 Mags

The Glock G45 Gen 6 P64550201 is a 9mm crossover pistol that combines a compact-length slide with a full-size frame. It uses a 4.02-inch Glock Marksman Barrel, black nDLC steel slide, optic-ready slide configuration, and a full-size polymer frame with an accessory rail.

That crossover layout is the defining feature of the G45. Rather than following the proportions of a traditional full-size or compact Glock exactly, the G45 pairs the shorter upper assembly with the longer grip and frame dimensions of Glock's full-size format.

The Gen 6 configuration adds revised grip ergonomics, an interchangeable backstrap system, refined frame texture, a flat-faced trigger, ambidextrous controls, and Glock's Safe Action system. This exact P64550201 package includes three 10-round magazines.

Compact-Length Slide with Full-Size Frame

The G45 Gen 6 uses a compact-length slide over a full-size polymer frame. That combination gives the pistol a shorter upper assembly while preserving the longer grip surface of Glock's full-size format.

The frame layout is what separates the G45 from Glock models built entirely around compact or full-size dimensions. The grip, magazine well, and control placement remain full-size even though the slide and barrel are shorter.

4.02-Inch Glock Marksman Barrel

The P64550201 uses a 4.02-inch Glock Marksman Barrel. The barrel length is matched to the compact-length slide that defines the upper half of the G45 configuration.

The Glock Marksman Barrel remains part of the factory Gen 6 setup rather than an aftermarket upgrade.

Gen 6 Ergonomic Frame

The Gen 6 frame incorporates revised grip ergonomics, refined texture, and an interchangeable backstrap system. These changes allow the grip to be configured around different hand sizes while retaining the full-size G45 frame dimensions.

The frame also includes an accessory rail for compatible lights and other rail-mounted accessories.

Flat-Faced Trigger

The G45 Gen 6 uses Glock's updated flat-faced trigger design. The flatter trigger face changes the contact surface under the shooter's finger compared with the more curved profile used on earlier Glock generations.

The trigger remains part of Glock's Safe Action operating system.

Optic-Ready Serrated Slide

The steel slide is factory configured for compatible pistol-mounted optics and uses a black nDLC finish. The optics-ready system allows the pistol to be set up with a compatible red-dot sight using the correct mounting system and hardware.

Front and rear slide serrations provide additional gripping surfaces for manual slide manipulation, while fixed Glock sights remain installed for conventional use.

Ambidextrous Controls

The G45 Gen 6 uses ambidextrous controls intended to make the pistol more adaptable to left- or right-handed operation.

That control layout is part of the broader Gen 6 ergonomic update rather than a separate aftermarket modification.

10-Round Magazine Configuration

This P64550201 is the 10-round configuration of the G45 Gen 6 and includes three 10-round magazines.

The reduced-capacity magazine setup allows the pistol to retain the full-size G45 frame and compact-length upper while using a 10-round magazine format.

The G45 Gen 6 Crossover Configuration

The G45 Gen 6 is defined by the relationship between its compact-length upper and full-size frame. The 4.02-inch Glock Marksman Barrel and shorter slide establish the upper dimensions, while the longer frame preserves the grip size and handling characteristics of Glock's full-size format.

In P64550201 form, that crossover design is paired with the Gen 6 ergonomic frame, refined grip texture, interchangeable backstraps, flat-faced trigger, ambidextrous controls, optic-ready slide, and black nDLC finish. The three included 10-round magazines complete this restricted-capacity configuration without changing the core proportions that define the G45.
