The Glock 22, a popular .40 S&W handgun, offers versatility through conversion barrels. These barrels allow you to switch calibers, often to 9mm, expanding the gun's capabilities. However, using a conversion barrel isn't always smooth sailing. This guide explores common problems encountered with Glock 22 conversion barrels and offers practical solutions.
Common Issues with Glock 22 Conversion Barrels
Several issues can arise when using a conversion barrel in your Glock 22. These problems range from minor inconveniences to potentially dangerous malfunctions. Let's delve into the most frequently reported problems:
1. Feeding Problems: Failure to Feed or Failure to Eject
This is arguably the most prevalent issue. The different cartridge dimensions (9mm vs. .40 S&W) mean the conversion barrel interacts differently with the magazine and the slide. This can lead to:
- Failure to feed: The round doesn't properly chamber.
- Failure to eject: The spent casing becomes stuck in the chamber.
Causes: This often stems from compatibility issues between the conversion barrel, magazine, and the Glock's internal mechanisms. A poorly manufactured barrel, a magazine not designed for the conversion, or even excessive wear on the gun can contribute.
Solutions:
- Ensure compatibility: Verify that the conversion barrel and magazine are specifically designed for your Glock 22 and the intended caliber (usually 9mm). Using an incorrect magazine is a frequent culprit.
- Clean and lubricate: A clean and well-lubricated firearm is essential for reliable function. Pay close attention to the barrel, chamber, and feed ramp.
- Magazine adjustments: Some conversion magazines may require minor adjustments to the follower or spring tension. Consult the manufacturer's instructions or a qualified gunsmith.
- Replace parts: If the problem persists, consider replacing the conversion barrel or the magazine.
2. Accuracy Issues: Reduced Accuracy or Inconsistent Grouping
While a conversion barrel shouldn't drastically reduce accuracy, some users report less precise shooting than with the factory barrel.
Causes: The slight differences in dimensions between conversion and factory barrels can affect bullet alignment and stability, potentially affecting accuracy. Poor-quality conversion barrels can exacerbate this issue.
Solutions:
- Proper sight adjustment: Ensure your sights are properly aligned for the new caliber. This often requires re-zeroing your weapon.
- Ammunition selection: Use high-quality ammunition designed for the conversion caliber. Poor-quality or inconsistent ammo can negatively impact accuracy regardless of the barrel.
- Barrel replacement: If accuracy remains consistently poor, a replacement conversion barrel from a reputable manufacturer might be necessary.
3. Reliability Issues: Malfunctions and Jams
Conversion barrels can sometimes lead to malfunctions, such as stovepipes, slide lock failures, or other jams.
Causes: These issues can be linked to various factors, including the aforementioned feeding problems, improper lubrication, and incompatibility with certain ammunition types.
Solutions:
- Thorough cleaning: Regularly clean and lubricate your Glock 22, paying particular attention to the barrel, feed ramp, and ejection port.
- Ammunition testing: Experiment with different types and brands of ammunition to identify if any specific type causes issues.
- Professional inspection: If malfunctions persist, have a qualified gunsmith inspect your firearm. They can identify any underlying problems with the conversion barrel, the gun itself, or related components.
Choosing a Reputable Conversion Barrel Manufacturer
The quality of the conversion barrel significantly impacts reliability and performance. Select a reputable manufacturer with a history of producing high-quality products. Research reviews and seek recommendations before purchasing a conversion barrel.
