Glock 22 High Cap Magazine: Extended and High-Capacity .40 S&W Magazines

A Glock 22 high cap magazine is an extended-capacity .40 S&W magazine that holds more than the standard 15 rounds for the full-size Glock 22. The term "high capacity" in the firearms industry refers to any magazine that exceeds the factory standard capacity. The Glock 22 OEM standard magazine holds 15 rounds of .40 S&W. Extended options include 22-round OEM magazines, 31-round aftermarket magazines, and 50-round drum magazines. TactaBlue stocks Glock 22 high cap magazines from Glock OEM, KCI, RWB, ETS Group, and ProMag.

Glock 22 Magazine Capacity Options

There are 5 capacity tiers for Glock 22 .40 S&W magazines:

• 10-round state-compliant magazines for restricted jurisdictions
• 15-round standard OEM flush-fit magazines
• 22-round OEM extended magazines
• 31-round aftermarket extended magazines (KCI, RWB)
• 50-round aftermarket drum magazines (RWB)

Glock 22 Standard 15-Round Magazine

The Glock 22 OEM 15-round magazine is the factory standard flush-fit .40 S&W magazine that sits flush with the full-size G22 grip. The 15-round magazine uses a double-stack configuration with a polymer body, hardened steel insert, steel-lined feed lips, and a coated compression spring. All Glock 22 generations (Gen 1 through Gen 5) use the same magazine dimensions and are cross-compatible.

Glock 22 Extended Magazine Options

Glock OEM 22-Round Extended Magazine

The Glock OEM 22-round .40 S&W extended magazine adds 7 rounds beyond the standard 15-round capacity. The 22-round magazine extends approximately 2.5 inches (64 mm) below the standard flush-fit floor plate. The OEM extended magazine uses the same polymer-and-steel construction as the standard magazine with a longer body and heavier spring.

KCI Glock .40 S&W 31-Round Magazine

The KCI Glock .40 S&W 31-round magazine fits the Glock 22, Glock 23, Glock 27, and Glock 35. The KCI Gen 2 magazine uses a polymer body with steel-lined feed lips and an anti-tilt follower. The 31-round magazine more than doubles the standard 15-round capacity.

RWB Glock .40 S&W 31-Round Magazine

The RWB (Red, White, and Blue) Glock .40 S&W 31-round magazine is an aftermarket polymer magazine available in black and tan (FDE) finishes. RWB magazines use a steel-lined polymer body for durability.

RWB Glock .40 S&W 50-Round Drum Magazine

The RWB Glock .40 S&W 50-round drum magazine is the highest capacity option available for the Glock 22 platform. The drum magazine uses a rotary-feed design that sits below the grip and extends forward.

Glock 22 Magazine Compatibility

The Glock 22 .40 S&W magazine is compatible with 4 other Glock models: the Glock 23 compact (magazine extends below grip), the Glock 27 subcompact (magazine extends below grip), the Glock 35 competition (flush-fit), and the Glock 24 (long-slide). The Glock 23 13-round magazine fits the Glock 22 but does not fill the full-size grip. Glock 22 .40 S&W magazines are not compatible with 9mm models (G17, G19) or .357 SIG models (G31).

Glock Advanced Magazine Technology

Glock OEM magazines use advanced magazine technology that includes a hardened steel insert encased in a polymer shell, steel-lined feed lips that resist spreading under cycling stress, and a coated compression spring rated for 10,000+ loading cycles. The polymer body absorbs impact force that would dent an all-metal magazine. The steel-lined feed lips maintain consistent cartridge presentation to the chamber across the magazine's service life.

State Magazine Capacity Laws

Glock 22 high cap magazines that exceed 10 or 15 rounds are restricted in states with magazine capacity limits. Ten states and the District of Columbia restrict magazine capacity. California, Connecticut, Maryland, Massachusetts, New Jersey, and New York limit magazines to 10 rounds. Colorado limits magazines to 15 rounds. Vermont limits magazines to 15 rounds for long guns (handgun magazines are exempt). Verify state and local legality before purchasing extended-capacity magazines.

Glock 22 Magazine Accessories

Glock 22 magazine accessories include +2 base plate extensions that increase the 15-round standard magazine to 17 rounds, magazine loaders for the .40 S&W cartridge, and magazine pouches. A Glock magwell funnels the magazine into the G22 grip for faster reloads. An extended slide release pairs with high-capacity magazines for faster manipulation.
