GLOCK G45 V 9mm 17+1 4.02″ Full-Size Frame Pistol
The GLOCK G45 V 9mm combines the comfortable grip and handling characteristics of a full-size handgun with the shorter slide and barrel dimensions of GLOCK’s compact platform. This crossover design creates a highly versatile 9mm pistol suitable for home defense, range shooting, training, duty applications and general-purpose firearm ownership.
Chambered in 9mm Luger, the G45 V features an approximately 4.02-inch barrel and a full-size frame capable of accepting a 17-round magazine. With a round chambered, this configuration provides a 17+1 capacity, giving shooters substantial ammunition capacity while maintaining the shorter overall slide profile of the G45 platform.
The defining characteristic of the GLOCK G45 is its crossover configuration.
Instead of pairing a compact slide with a compact grip, the G45 combines a compact-length slide with a full-size frame. The larger grip provides plenty of surface area for a secure firing grip, while the shorter slide helps keep the pistol maneuverable and well balanced.
This combination makes the G45 V a strong option for shooters looking for a handgun capable of filling multiple roles.
Common applications include:
- Home and personal defense
- Range shooting
- Firearms training
- Duty and professional use
- Vehicle or emergency preparedness
- General-purpose handgun ownership
- 17+1 Capacity
This configuration of the GLOCK G45 V includes a 17-round magazine, providing a 17+1 capacity when loaded with an additional round in the chamber.
The combination of standard full-size magazine capacity and the G45’s shorter slide is a major advantage of the crossover platform.
For defensive, duty, and range applications, the 17-round capacity provides shooters with the ammunition capacity expected from a modern full-size 9mm handgun.
Full-Size Grip
The G45 V uses a full-size grip frame, providing additional gripping surface compared with traditional compact GLOCK models.
For shooters with larger hands or those who simply prefer the feel of a full-size pistol, the longer grip can provide a comfortable and secure shooting platform.
The larger frame also accommodates the G45’s 17-round magazine while maintaining the shorter slide assembly that distinguishes the crossover design.
4.02-Inch Barrel
The GLOCK G45 V features an approximately 4.02-inch barrel, giving the pistol the compact-length upper assembly that helps define the G45 platform.
The shorter slide and barrel help create a pistol that feels maneuverable without sacrificing the full-size grip and magazine capacity many shooters prefer.
With an overall length of approximately 7.44 inches, the G45 V sits between traditional compact and full-size handgun configurations.
Front Slide Serrations
The G45 V features front and rear slide serrations, providing multiple gripping surfaces for manipulating the slide.
The additional front serrations can be useful during loading, unloading, chamber checks and other routine firearm manipulations.
GLOCK Safe Action® System
The G45 V incorporates GLOCK’s established Safe Action® System, which uses three independently operating passive mechanical safeties.
These safeties disengage sequentially as the trigger is intentionally pulled and automatically re-engage when the trigger is released.
The system eliminates the need for a traditional external manual safety lever while providing the consistent operation that has become one of the defining characteristics of GLOCK pistols.
A Versatile Full-Size 9mm
The combination of a full-size grip, 17+1 capacity, compact-length slide and 9mm chambering makes the G45 V a versatile handgun for shooters who don’t necessarily want to choose between compact handling and full-size capability.
For home defense, professional applications, training or regular range use, the G45 V provides the familiar simplicity and reliability associated with the GLOCK platform in a practical crossover configuration.
If you’re looking for a GLOCK 9mm with 17+1 capacity and a 4-inch barrel, the GLOCK G45 V offers a strong balance of capacity, handling and overall size.
