Glock 27 pistols, known for their compact size and reliability, are popular choices for concealed carry. However, converting them to shoot different calibers using conversion barrels can sometimes lead to problems. This article delves into the common issues encountered with Glock 27 conversion barrels, offering solutions and preventative measures. Understanding these potential problems is crucial for maintaining firearm safety and ensuring reliable performance.
Understanding Glock 27 Conversion Barrels
Glock 27 conversion barrels allow shooters to switch between calibers, often from the pistol's native .40 S&W to 9mm or .357 SIG. This versatility is appealing, but it's essential to recognize that these barrels are not always a perfect fit. The design changes required to accommodate different cartridge dimensions can introduce challenges. The term "conversion barrel" refers to a replacement barrel designed to fire a caliber different from the pistol's original design. These are available from various manufacturers, and quality can vary significantly. Choosing a reputable manufacturer is critical.
Common Glock 27 Conversion Barrel Problems
Several issues can arise when using conversion barrels with a Glock 27. These range from minor inconveniences to potentially dangerous malfunctions.
1. Feed Issues and Jams
This is perhaps the most frequent complaint. The different cartridge dimensions, particularly the case length and diameter, can cause problems with feeding from the magazine. Improper seating of the cartridge in the chamber can lead to stovepipes, failure to feed, or double feeds. This is exacerbated by the Glock 27's smaller frame, which leaves less tolerance for variations in cartridge dimensions.
Solutions:
- Use high-quality ammunition: Consistent, properly lubricated ammunition is crucial. Avoid reloads or ammunition known for inconsistencies.
- Check magazine compatibility: Ensure your magazines are compatible with the chosen caliber. Some magazines may not function reliably with conversion barrels.
- Consider aftermarket magazine springs: A stiffer magazine spring might improve feeding reliability.
- Inspect the barrel for damage or wear: A damaged or worn barrel can contribute to feeding issues.
2. Accuracy Problems
While some shooters report acceptable accuracy with conversion barrels, others experience decreased accuracy compared to the factory barrel. This is often attributed to the manufacturing tolerances of the conversion barrel and the potential for slight misalignment within the pistol's slide.
Solutions:
- Proper break-in period: Fire a significant number of rounds through the conversion barrel to allow for proper break-in.
- Professional gunsmithing: A qualified gunsmith can assess the barrel's alignment and make necessary adjustments.
3. Increased Recoil
The change in cartridge weight and power can result in increased recoil. This is especially noticeable in smaller frame pistols like the Glock 27.
Solutions:
- Practice and proper technique: Proper grip and stance are essential to manage increased recoil.
- Consider recoil-reducing accessories: While not always effective, recoil-reducing grips or buffers may provide some improvement.
4. Headspace Problems
Incorrect headspace is a serious safety concern. This occurs when there's insufficient or excessive distance between the cartridge case head and the breech face. Incorrect headspace can lead to catastrophic failures. This emphasizes the need for thorough inspection of the barrel and the cartridge's placement in the chamber.
Solutions:
- Do not use a conversion barrel unless you are certain of its compatibility and safety: Consult a qualified gunsmith or a reputable source to verify proper headspace.
- Regular inspection: Regularly check the conversion barrel for any signs of wear or damage.
5. Extractor Issues
The extractor, responsible for pulling the spent casing from the chamber, may struggle with different caliber cases.
Solutions:
- Use a properly tuned extractor: Some aftermarket extractors are designed for specific conversion barrels.
Choosing a Reputable Conversion Barrel Manufacturer
The quality of the conversion barrel significantly impacts its reliability and safety. Always purchase from a known and reputable manufacturer. Thorough research before buying is recommended, reading reviews and checking for any reported issues with specific brands.
Conclusion
While Glock 27 conversion barrels offer the allure of caliber versatility, they do present potential problems. Understanding these potential issues, exercising caution, choosing high-quality products, and prioritizing firearm safety are paramount. Always prioritize safety and reliability above convenience. If you have any concerns or experience any problems, seek the guidance of a qualified gunsmith.
