Clips for Glock 23: OEM and Aftermarket .40 S&W Magazines for Gen 1-5

Glock 23 magazines (commonly searched as "clips for Glock 23") are double-stack, polymer-bodied ammunition feeding devices that hold 13 rounds of .40 S&W and insert into the compact Glock 23 grip. The term "clip" in firearm terminology refers to a stripper clip or en-bloc clip, not a detachable box magazine. The correct term for the Glock 23 ammunition feeding device is "magazine." The OEM Glock 23 magazine measures 2.87 inches (73 mm) in length and uses the same compact frame dimensions as the Glock 19 9mm magazine. TactaBlue stocks Glock 23 magazines from Glock OEM, ETS Group, and ProMag in standard and extended capacities.

The Glock 23 fires .40 S&W (Smith & Wesson) ammunition. The .40 S&W cartridge is wider than 9x19mm, which means Glock 23 magazines are not interchangeable with Glock 19 9mm magazines despite sharing the same compact frame. The .40 S&W feed lip geometry, follower width, and spring rate differ from 9mm specifications.

Glock 23 Magazine Capacity Options

There are 4 OEM Glock 23 magazine capacity configurations:

• 10-round state-compliant magazines for restricted jurisdictions
• 13-round standard flush-fit magazines that sit flush with the compact G23 grip
• 15-round magazines using the full-size Glock 22 magazine that extends below the G23 grip
• 22-round extended magazines for range and home defense

Aftermarket extended magazines from ETS Group and ProMag are available in 22-round and 30-round configurations for the Glock 23 in .40 S&W.

Glock 23 Magazine Compatibility

The Glock 23 magazine is compatible with 3 other Glock models in .40 S&W: the Glock 27 subcompact (extends below grip), the Glock 22 (G23 magazine functions but does not fill the full-size grip), and the Glock 35 competition model. The full-size Glock 22 15-round magazine fits the Glock 23 and extends below the compact grip. Glock 23 magazines are not compatible with 9mm models (G19, G17, G26) or .357 SIG models (G32) without caliber-specific components.

Glock 23 Generation History

Glock has produced 5 generations of the Glock 23. Gen 1 introduced the compact .40 S&W platform. Gen 2 added checkered texture. Gen 3 (1998) introduced the accessory rail and finger grooves. Gen 4 (2010) added modular backstraps, a reversible magazine catch, and a dual recoil spring assembly. Gen 5 (2017) removed finger grooves and added the flared magwell. All Glock 23 magazines from Gen 1 through Gen 5 are cross-compatible.

Glock 23 vs. Glock 19 Magazines

The Glock 23 and Glock 19 share the same compact frame dimensions but use different magazines that are not interchangeable. The Glock 23 .40 S&W magazine is wider internally to accommodate the larger .40 caliber cartridge (10.2mm case diameter vs. 9.93mm for 9x19mm). The Glock 23 holds 13 rounds vs. 15 rounds in the Glock 19 magazine because the .40 S&W cartridge is wider.

Glock 23 Magazine Maintenance

Inspect Glock 23 magazine feed lips for visible spreading or cracking every 3,000 rounds. The .40 S&W cartridge produces higher feed lip stress than 9mm due to the wider cartridge and higher chamber pressure (35,000 psi for .40 S&W vs. 35,000 psi for 9mm +P). Replace the magazine spring every 8,000 to 10,000 rounds for consistent feeding. Clean magazines after exposure to dirt, sand, or moisture.

Glock 23 Magazine Accessories

Glock 23 magazine accessories include base pad extensions (+2, +3 capacity), magazine loaders, and magazine pouches. The Glock magwell funnels the magazine into the G23 grip for faster reloads. An extended slide release complements the magazine upgrade for faster slide manipulation. A binary trigger is available for the Glock 23 Gen 3 (Franklin Armory G-S223).
