Will a Glock 22 Mag Fit a Glock 27?

Gun enthusiasts often wonder if Glock 22 magazines can be used in a Glock 27. Both are popular models, with the Glock 22 being chambered in .40 S&W, and the Glock 27 being chambered in .40 S&W subcompact. It’s not uncommon for gun owners to have several firearms chambered in the same caliber, and they may wonder if it’s possible to use the same magazines across different models. In this article, we explore whether a Glock 22 magazine can fit a Glock 27.

Comparison of Glock 22 and Glock 27

Glock 22 is a full-size pistol with a 4.49-inch barrel, while the Glock 27 is a subcompact model with a 3.42-inch barrel. The Glock 22 has a capacity of up to 15 rounds, while the Glock 27 has a capacity of up to 9 rounds. The trigger system, sights, and magazine release are the same in both models. However, the Glock 22 is slightly heavier than the Glock 27, weighing 25.59 ounces unloaded, while the latter weighs 21.89 ounces unloaded.

Despite some minor differences, both Glock models are renowned for their reliability, accuracy, and durability. They are both popular choices for law enforcement, security personnel, and private citizens as well.

Mechanics of Glock 22 and Glock 27 Magazines

The magazine of a Glock pistol is an essential component that feeds rounds into the firearm’s chamber. Glock 22 and Glock 27 magazines are designed to fit each specific model. Glock magazines also have a metal spring that applies pressure to the rounds, pushing them up into the chamber. Glock magazines also have an anti-tilt follower, which prevents jams caused by an uneven distribution of pressure on the rounds. It’s essential to have reliable magazines for any Glock pistol to function and perform optimally.

The difference in magazine capacity can be contributed to the variation in the Glock models’ sizes. Glock 22 magazines are designed for full-size models and come in 15, 22, and 31 round capacities. Glock 27 magazines are specifically designed for subcompact models and come in 9, 10, and 22 round capacities. As a result, the magazines are of different lengths, widths, and heights.

Types of Magazines Available for Glock 22 and Glock 27

Glock is an incredibly popular firearm, and the company manufactures many different types of magazines to fit its various pistol models. There are two primary types of Glock magazines; factory and aftermarket magazines. Factory magazines are made by Glock and are the most reliable and highest quality magazines a user can buy. Aftermarket magazines are produced by other companies, and their quality varies widely.

The good news is that Glock has a reputation for quality, and factory magazines produced for one Glock model are generally interchangeable with other Glock models. Glock 22 magazines can be used in other full-size Glock models such as the Glock 23 and Glock 35. Similarly, Glock 27 magazines are compatible with other subcompact models such as the Glock 26 and the Glock 33.

Pros and Cons of Using Different Magazines

Using different types of magazines in Glock 22 and Glock 27 firearms can have its benefits and drawbacks. The primary advantage of using one magazine in multiple firearms is the ease of use, as you don’t have to swap out magazines every time you switch firearms. However, using a single magazine might not be ideal if the magazine is not designed specifically for the firearm in use.

Aftermarket magazines are less reliable than factory magazines. Factory magazines are of higher quality, have more consistent feeding and longevity, and have the backing of the company. Although aftermarket magazines tend to be cheaper, they are not worth the money saved if they fail to work correctly.


In conclusion, using a Glock 22 magazine in a Glock 27 may not be safe, reliable or practical. Although similar, they are different models with different magazine sizes. Glock 22 magazines are made for full-size models and Glock 27 custom magazines to subcompact models. Using the wrong type of magazine may cause feeding, reliability, and safety issues. Glock’s reputation for producing high-quality firearms and reliable factory magazines is one of the reasons for its popularity. As a gun owner, it is essential to buy the correct magazines that are designed precisely for the firearm you own.

If you are considering using multiple types of magazines for your Glock firearms, it’s essential to stick with factory magazines for the highest quality and reliability. Investing in quality accessories for your firearm is worthwhile in the long run, both in terms of performance and safety.
