The Glock 22, a .40 S&W powerhouse, enjoys considerable popularity among law enforcement and civilian shooters alike. However, the rising cost and sometimes limited availability of .40 S&W ammunition have led many owners to explore conversion options for firing 9mm Luger. This guide dives deep into the Glock 22 9mm conversion, covering everything from the necessary components to potential pitfalls and considerations.
Understanding the Glock 22 9mm Conversion Process
Converting a Glock 22 to fire 9mm isn't about simply swapping out the magazine. It's a more involved process requiring specific components designed for reliable operation with the smaller caliber. The key element is the conversion barrel, but you'll also need a 9mm magazine. Let's break it down:
1. The Conversion Barrel: The Heart of the Conversion
The conversion barrel is the most crucial component. It's specifically designed to fit the Glock 22's slide and chamber the 9mm Luger cartridge. Crucially, it needs to be manufactured to exacting tolerances to ensure reliable feeding, chambering, and extraction. Using a poorly made or improperly fitted barrel can lead to malfunctions, jams, and potentially dangerous situations. Always purchase from a reputable manufacturer with a proven track record.
2. The 9mm Magazine: Capacity and Reliability
You'll also need a magazine designed for 9mm cartridges. Glock 22 magazines are incompatible with 9mm rounds. The 9mm magazines for the Glock 17 or Glock 19 will generally function correctly in a Glock 22 converted to 9mm, but it's always advisable to test thoroughly to ensure reliable feeding.
3. No Conversion Spring Required: A Common Misconception
Unlike some conversion kits for other firearms, a dedicated conversion spring is typically not required for a Glock 22 9mm conversion. The existing recoil spring in your Glock 22 is usually sufficient for reliable cycling with 9mm ammunition. Using a different spring might affect reliability, potentially leading to malfunctions.
Potential Benefits of a Glock 22 9mm Conversion
- Cost Savings: 9mm Luger ammunition is generally less expensive than .40 S&W, making range time more affordable.
- Reduced Recoil: 9mm Luger has less recoil than .40 S&W, improving shooter comfort and control, especially for less experienced shooters.
- Increased Capacity: 9mm magazines often have higher capacity than .40 S&W magazines for the Glock 22.
Potential Drawbacks and Considerations
- Accuracy: While many shooters report no significant loss of accuracy, some may experience slight variations.
- Reliability: Using a low-quality conversion barrel can drastically impact reliability. Always prioritize quality components from reputable manufacturers.
- Legal Considerations: Check your local and state laws regarding firearm modifications and conversions before proceeding.
Choosing the Right Components: Quality Over Price
The Glock 22 9mm conversion is only as good as the quality of its components. Don't skimp on the barrel. Invest in a high-quality conversion barrel from a well-known manufacturer. Thoroughly research reviews and choose a reputable source for your 9mm magazines as well. Improperly fitting parts can lead to malfunctions, impacting accuracy and even creating potentially dangerous situations.
Safety First: Thorough Testing and Professional Guidance
Before carrying or relying on your converted Glock 22 for self-defense, thoroughly test it with various types and brands of 9mm ammunition. Pay close attention to function, feeding, extraction, and ejection. If you're not comfortable with the process, seek guidance from a qualified gunsmith experienced with Glock modifications. Remember, safety should always be your top priority.
