That’s where the Glock 22 9mm barrel conversion enters the picture.
This article delves into the world of converting your Glock 22 to shoot 9mm ammunition. We’ll explore the reasons why you might consider this modification, the crucial components involved, the installation process, and the impact on your firearm’s performance. We’ll cover everything you need to know to make an informed decision and successfully convert your Glock 22.
Understanding the Glock 22
The Glock 22, manufactured by Glock GmbH, is a cornerstone of modern handgun design. Its polymer frame reduces weight and increases its resistance to the elements. The pistol’s design incorporates a relatively simple, safe, and reliable internal mechanism, a design that contributes significantly to its widespread adoption. Key features include a short recoil operated, locked-breech system, offering a robust and dependable action.
The original chambering for the Glock 22 is .40 Smith & Wesson (.40 S&W). This cartridge offers a significant ballistic advantage over the more common 9mm Luger round, making it a popular choice for law enforcement and self-defense purposes. The .40 S&W round typically offers excellent energy transfer and stopping power, though some may find the recoil somewhat more assertive compared to other pistol calibers.
The Glock 22’s popularity stems from several factors. These include its reputation for reliability, its ease of maintenance, and its availability of aftermarket parts and accessories. The Glock platform, in general, is celebrated for its modularity, allowing for significant customization. Its simple takedown process and user-friendly design contribute to its appeal, making it a suitable choice for both experienced shooters and those new to firearms.
The 9mm Conversion: Why and When
There are compelling reasons why a Glock 22 owner might contemplate a 9mm conversion. One of the most significant is the cost of ammunition. 9mm Luger ammunition is, in most instances, significantly less expensive than .40 S&W. This difference can translate into substantial savings, particularly if you are a frequent shooter. More affordable ammunition makes more range time, or practice more accessible, without breaking the bank.
The 9mm Luger round typically exhibits less felt recoil than the .40 S&W. This can translate into improved shot placement, faster follow-up shots, and a more comfortable shooting experience. The reduced recoil may be especially noticeable for shooters who are new to handguns, or those who find the .40 S&W round challenging to manage.
The availability of 9mm ammunition is another consideration. 9mm is one of the most widely produced and available pistol cartridges in the world. It’s readily accessible at nearly any gun store or online retailer. While .40 S&W is also readily available, the ubiquitous presence of 9mm can offer peace of mind during ammunition shortages or supply chain disruptions.
The Glock 22 9mm barrel conversion is best suited for certain situations. For example, it’s an excellent option for dedicated range practice. The cost savings and reduced recoil make it ideal for spending extended periods at the range, working on your shooting skills. The conversion can also be a practical choice for training exercises where the goal is to improve marksmanship and firearms handling, not necessarily terminal ballistics.
Barrel Compatibility: The Core of the Conversion
At the heart of the Glock 22 9mm conversion lies the barrel itself. Since the .40 S&W and 9mm Luger cartridges have different dimensions, using a dedicated Glock 22 9mm barrel is essential for safe and proper function. A quality barrel is a must to ensure proper headspace and rifling engagement with the projectile.
There are several types of Glock 22 9mm barrels to consider. The “drop-in” barrel is the most straightforward. These barrels are designed to fit directly into the Glock 22 slide, requiring no modifications to the firearm. Drop-in barrels offer ease of installation, making them popular for those seeking a quick conversion. Be aware that while typically fine, slight variations in accuracy might be experienced as drop-in barrels may not always have perfect lockup.
Another option is a threaded barrel. Threaded barrels extend beyond the slide’s front end and feature threads designed to accommodate suppressors or muzzle devices, such as compensators. While not always necessary, threaded barrels can provide increased versatility, allowing for customization to match your shooting needs and preferences.
The aftermarket offers numerous choices for Glock 22 9mm barrels. Many reputable manufacturers provide various options, and the Glock OEM (Original Equipment Manufacturer) barrel is a good choice. These aftermarket barrels can offer enhanced features such as tighter tolerances, different rifling profiles, and a wider range of finish options. Research and compare different barrel brands to determine which best suits your needs.
Choosing a Glock 22 9mm barrel requires careful consideration. Key factors include the type of rifling (conventional or polygonal), the material used (typically stainless steel or carbon steel), and the barrel’s overall finish. The rifling profile, for example, can affect the barrel’s performance and accuracy. Barrel finishes, like nitride or DLC (Diamond-Like Carbon), can provide increased durability and resistance to wear and corrosion.
Other Essential Components and Modifications
Beyond the Glock 22 9mm barrel itself, a successful conversion might necessitate the use of other components.
One of the required changes is magazine compatibility. Since the .40 S&W magazines and 9mm magazines are shaped differently, using 9mm magazines is essential. Simply stated, .40 S&W magazines will not feed 9mm ammunition reliably. Therefore, you will need to acquire magazines specifically designed for the 9mm Luger cartridge. This is a critical component of a functional conversion.
Regarding the recoil spring assembly (RSA), there is some debate. Some shooters find the .40 S&W RSA functions well with a 9mm barrel. However, others recommend using a 9mm RSA. A 9mm-specific RSA typically features a different spring rate, which can better match the lower recoil of the 9mm Luger round. This can lead to increased reliability and reduced wear on the firearm. If you frequently experience malfunctions, consider trying a 9mm-specific RSA to see if it resolves the issue.
Installation Process and Safety Precautions
Installing a Glock 22 9mm barrel is generally a straightforward process. Always ensure the firearm is unloaded, the magazine is removed, and the chamber is clear.
Begin by disassembling the Glock 22. This involves removing the slide from the frame, removing the original .40 S&W barrel, and then installing the 9mm barrel. The process typically involves these steps:
1. Clear the firearm and confirm it is unloaded.
2. Remove the slide from the frame.
3. Depress the firing pin safety and remove the slide stop lever.
4. Remove the recoil spring assembly.
5. Remove the original .40 S&W barrel from the slide.
6. Insert the Glock 22 9mm barrel.
7. Reassemble the slide and frame.
Always consult the manufacturer’s instructions for your specific barrel model. Proper installation and assembly are critical for the safe and reliable operation of the firearm.
Safety is paramount during the installation. Double-check that the firearm is unloaded at every stage. Wear appropriate eye protection and consider wearing gloves.
After installing the 9mm barrel, perform a function check to ensure everything operates as it should. Cycle the slide multiple times to ensure proper feeding, extraction, and ejection. If possible, use dummy rounds to test the system. After the initial function check, consider testing the converted Glock 22 at the range. This will enable you to identify any potential problems before they become a safety concern.
Accuracy, Reliability, and Performance
The accuracy you can expect with a Glock 22 9mm barrel is often excellent. The inherent accuracy of the Glock platform, combined with a quality 9mm barrel, can deliver impressive results. The potential for increased accuracy comes from the barrel’s quality and the shooter’s skill. However, with the right barrel and proper technique, impressive groupings are possible.
During initial testing, you may encounter some issues. Failures to feed, failures to extract, or ejection problems may occur. If these issues arise, inspect the firearm and the magazines thoroughly. Ensure the magazines are clean and functioning properly. Inspect the extractor and ejector for any signs of damage or wear. The proper functioning of the recoil spring assembly is critical to these functions.
If malfunctions persist, experiment with different types of 9mm ammunition. Some Glock 22 9mm barrels may prefer specific bullet weights or bullet profiles. Consult with the barrel manufacturer or gunsmith for troubleshooting assistance if necessary.
