1. Overview of the GLOCK 22 .40 S&W Pistol

Introduced in the early 1990s, the GLOCK 22 quickly became one of the most popular duty weapons in the United States. Its chambering in .40 S&W — a caliber designed specifically to bridge the gap between 9mm and .45 ACP — provides a superior combination of velocity, penetration, and energy transfer.

Law enforcement agencies across the country adopted the GLOCK 22 for its:

• High magazine capacity compared to other .40 caliber pistols

• Proven GLOCK durability in extreme conditions

• Simple operation with GLOCK’s Safe Action® System

• Light polymer frame reducing carry fatigue

4. Performance Review

Accuracy

The GLOCK 22 is designed for combat accuracy — precise enough for defensive engagements at typical ranges while still capable of consistent groups at 25 yards. The sight radius and barrel length provide a steady sight picture, and the low bore axis helps manage recoil.

Recoil Management

The .40 S&W generates more recoil than a 9mm, but the GLOCK 22’s polymer frame flex, ergonomic grip, and balanced weight help tame muzzle rise. This allows for quick follow-up shots during defensive drills or competition.

Trigger Feel

The Safe Action® trigger offers a consistent pull with a crisp break and short reset, essential for rapid shooting under pressure.

Durability

From saltwater exposure to sand immersion tests, the GLOCK 22 performs reliably. It’s not just marketing hype — decades of police use have proven this pistol’s resilience.
