Glock 22 Gen4 — Duty-Proven Performance in .40 S&W

GLOCK 22 Gen4 Semi-Auto Pistol

The Glock 22 Gen4 is a full-size, striker-fired, semi-automatic pistol chambered in .40 S&W. For decades, it served as a staple duty sidearm for law enforcement agencies across the United States, valued for its blend of capacity, power, durability, and simple manual of arms. The Gen4 updates improved ergonomics and recoil management while preserving the rugged reliability the model is known for.

If you’re researching whether the Glock 22 Gen4 is a good choice, how it operates, what it can (and cannot) shoot, and how it compares to other Glock models, this guide answers those questions clearly while giving you a complete product overview.

Full-size polymer-frame pistol
Chambered in .40 S&W
Striker-fired, semi-automatic action
Double-stack magazine design
Gen4 features: Modular Back Strap System, Rough Textured Frame (RTF), dual recoil spring assembly, reversible magazine release

The Glock 22 is often considered the flagship .40 S&W Glock, equivalent in size to the Glock 17 in 9mm.

Is a Glock 22 Semi Automatic?

Yes. The Glock 22 Gen4 is a semi-automatic pistol. One round is fired per trigger press, and the slide cycles automatically to chamber the next round.

“Are Glock 22 Good?” / “Is the Glock 22 Gen 4 a Good Gun?”

These are extremely common search questions.

The Glock 22 Gen4 earned its reputation through:

Extensive law enforcement adoption
Proven reliability under heavy use
High magazine capacity for the caliber
Manageable recoil with Gen4 dual spring system
Long service life with minimal maintenance

Shooters who want a full-size pistol with more energy than 9mm and excellent durability often find the Glock 22 Gen4 a strong choice.

When Did Glock 22 Gen4 Come Out?

The Gen4 series was introduced around 2010, bringing ergonomic and recoil system improvements to existing Glock models, including the Glock 22.

Did Glock Discontinue the Gen 4?

Some Glock models transitioned to Gen5 in certain calibers and markets. However, many Gen4 pistols—including .40 S&W variants like the Glock 22—remain widely available and supported due to ongoing demand and agency use.

Shooting Performance and Recoil Control

GLOCK 22 Gen4 Semi-Auto Pistol

The .40 S&W cartridge has a reputation for “snappy” recoil compared to 9mm. The Gen4 improvements help mitigate this through:

Dual recoil spring assembly
Full-size frame weight
Aggressive grip texture for control
Wide grip surface distributing recoil forces

This makes the Glock 22 Gen4 more comfortable to shoot than earlier generations.

Do Glock 22 Have Safety?

Glock pistols, including the Glock 22 Gen4, do not have an external manual thumb safety. Instead, they use Glock’s internal Safe Action system:

Trigger safety lever
Firing pin safety
Drop safety

These automatic safeties disengage only when the trigger is deliberately pressed.

Caliber Questions — What Can a Glock 22 Shoot?

This is where many search queries appear, and accuracy matters.

Can a Glock 22 Shoot .45?

No. The Glock 22 is built specifically for .40 S&W. .45 ACP is a different size cartridge and requires a different platform.

Can Glock 22 Shoot 10mm?

No. 10mm Auto is longer and operates at different pressures. It is not compatible.

Can a Glock 22 Take 9mm?

Can a Glock 22 Shoot 9mm?

From the factory, the Glock 22 is designed for .40 S&W only. Some experienced users explore caliber conversions with aftermarket components, but the standard configuration is for .40 S&W. Always follow manufacturer specifications.

This question often refers to caliber confusion.

Glock does not make a .22 LR version of the Glock 22
Glock does produce .22 LR pistols in other models
The Glock 22 is named for the model number, not the caliber

Does Glock Have a .22 Caliber Handgun?

Yes, Glock manufactures .22 LR pistols in different models, but that is separate from the Glock 22, which is .40 S&W.
