When Glock announced the release of the Glock 45 in 2018, it raised eyebrows across the firearms community. At first glance, the Glock 45 might appear to be just another 9mm pistol, but dig deeper and you’ll discover that it’s a purpose-built platform that combines the best of Glock’s compact and full-size models.
So, is the Glock 45 worth the upgrade—especially if you already own models like the Glock 19 or Glock 17? This in-depth Glock 45 review explores its features, performance, and value to help you decide if this pistol belongs in your safe, your holster, or your duty rig.
What Is the Glock 45?
The Glock 45 is a crossover 9mm pistol that combines a Glock 17 full-size frame with a Glock 19 compact slide and barrel. This configuration delivers the shooting control of a full-sized grip with the maneuverability of a shorter slide—an ideal blend for duty use, self-defense, and even competitive shooting.
Unlike what the name suggests, the Glock 45 is not chambered in .45 ACP. Instead, it’s a Gen 5 9mm pistol packed with modern enhancements.

High-Performance Features of the Glock 45
1. Gen 5 Enhancements
As part of Glock’s Gen 5 family, the G45 benefits from significant upgrades over earlier generations, including:
nDLC Finish: Improved resistance to wear and corrosion
Glock Marksman Barrel (GMB): Enhanced accuracy
No Finger Grooves: Allows a better fit for different hand sizes
Ambidextrous Slide Stop: Friendly for left- and right-handed shooters
Flared Magwell: Faster reloads under stress
2. Crossover Design
The combination of a Glock 17 frame and a Glock 19 slide gives the G45 superior balance and excellent recoil management. This design allows for a full grip while reducing slide length for better maneuverability, especially when drawing from a holster.
3. MOS Variant
The Glock 45 MOS (Modular Optic System) version allows you to mount red dot optics like the Trijicon RMR or Holosun 507C with ease. This makes it a powerful option for both professional and civilian shooters who value faster target acquisition.
Glock 45 vs Glock 19: Which One Is Better?
One of the most common comparisons shooters make is between the Glock 45 vs Glock 19. Here’s a quick look:
| Feature | Glock 19 | Glock 45 |
|---|---|---|
| Frame Size | Compact | Full-size |
| Slide Length | Compact | Compact (same as G19) |
| Magazine Capacity | 15+1 | 17+1 |
| Concealability | Easier to conceal | Slightly harder due to grip |
| Recoil Control | Moderate | Improved due to full-size grip |
If concealed carry is your top priority, the G19 may still edge out. But if you want better recoil management, a higher capacity, and a more ergonomic grip, the Glock 45 wins hands down.
Performance at the Range
The Glock 45 9mm pistol shines in real-world shooting scenarios. Thanks to its GMB barrel and upgraded trigger system, shooters report tighter groupings and faster follow-up shots. The full-size grip offers better control, especially under rapid fire, while the shorter slide allows for quicker draw and sight alignment.
Key Performance Highlights:
Minimal recoil and muzzle flip
Exceptional reliability under all weather and ammo conditions
Fast target acquisition with optional optic mount on MOS version
Smooth trigger pull with crisp reset
Is the Glock 45 Good for Concealed Carry?
While the Glock 45 is larger than the average compact pistol, many users still find it manageable for everyday concealed carry, especially with the right holster and clothing. Its rounded edges and consistent Gen 5 grip texture help with concealment and comfort.
Recommended Holsters:
IWB (Inside the Waistband) Kydex Holsters
Appendix carry rigs with sweat guards
Shoulder holsters for under-jacket carry
For those willing to adapt, the Glock 45 makes a powerful, high-capacity concealed carry pistol.
