The Glock 22 (G22) is the .40 S&W counterpart to the Glock 17 and has been a staple of law enforcement for decades. Choosing a G22 setup involves more than just picking a holster; it requires an understanding of the caliber’s unique recoil, the modularity of the frame, and the maintenance requirements of a high-pressure system. If you are considering a G22 build or purchase, here are five critical facts to guide your setup.
1. Understanding the .40 S&W Recoil
The .40 S&W cartridge is known for a “snappy” recoil impulse compared to the 9mm. When setting up your G22, consider adding a heavier recoil spring or a tungsten guide rod. This extra weight at the front of the frame helps soak up the “snap,” allowing for faster follow-up shots. A proper grip is also more important on a G22, as the increased vibration can lead to “limp-wristing” malfunctions if not held firmly.
2. The Benefit of Caliber Conversions
One of the best things about a G22 setup is its versatility. Because the G22 uses a larger breech face, you can easily convert it to shoot 9mm or .357 SIG with a simple “Conversion Barrel” and the corresponding magazines. This essentially gives you three guns in one. Many owners use the .40 S&W for defense and switch to a 9mm barrel for cheaper practice at the shooting range.
3. Magazine Compatibility and Capacity
The G22 uses standard 15-round magazines, but it is also compatible with the 22-round “extended” magazines often used for competition. Interestingly, 9mm Glock 17 magazines will fit in the G22 frame, but they will not feed .40 S&W rounds reliably. When setting up your kit, ensure your magazines are clearly marked, especially if you use conversion barrels, to avoid the dangerous mistake of loading the wrong caliber into the wrong magazine.
4. Enhanced Maintenance Requirements
The .40 S&W is a high-pressure round that puts more stress on the firearm’s internals than a 9mm. When setting up a G22, you should plan on a more frequent “Parts Replacement” schedule. The recoil spring, trigger bar, and extractor should be inspected every 3,000 rounds. A G22 setup is incredibly durable, but neglecting these small springs can lead to a loss of reliability over the long term.
5. Holster and Accessory Interchangeability
Because the G22 shares the exact same exterior dimensions as the Glock 17, finding accessories is incredibly easy. Almost every holster, light, and laser designed for the 9mm G17 will fit the G22 perfectly. This makes the G22 an excellent “duty” setup, as you have access to the widest variety of professional-grade gear on the market. Just ensure that any “Slide Compensators” you buy are specifically bored for the .40 caliber bullet.
