The Glock 17, a mainstay in the world of handguns, is renowned for its reliability and versatility. While it's typically chambered in 9x19mm Parabellum, many shooters wonder about the possibility of converting their Glock 17 to fire the .40 S&W cartridge. This article explores the reality of Glock 17 .40 S&W conversion kits, their practicality, and what you should consider before undertaking such a modification.
Understanding Glock 17 .40 S&W Conversion Kits
The concept is simple: a conversion kit allows you to change the caliber of your Glock 17 from 9mm to .40 S&W. This typically involves swapping out several key components, including the barrel, magazine, and potentially the recoil spring and guide rod. However, it's crucial to understand that these kits don't magically transform your gun; they require careful installation and understanding of firearm mechanics. Improper installation can lead to malfunctions, damage to the firearm, and serious injury.
What's Included in a Typical Kit?
A complete Glock 17 .40 S&W conversion kit usually includes:
- .40 S&W Barrel: This is the most critical component, as it dictates the caliber the firearm will fire. Ensure the barrel is specifically designed for the Glock 17 and is from a reputable manufacturer.
- .40 S&W Magazine: 9mm magazines are incompatible with .40 S&W cartridges. The kit will supply a magazine designed for the .40 S&W round.
- (Sometimes Included) Recoil Spring and Guide Rod: The .40 S&W round has a higher recoil than the 9mm, so a heavier recoil spring might be necessary for reliable function. Check the kit's specifications.
The Reality Check: Is it Worth It?
While the idea of easily switching calibers is appealing, converting a Glock 17 to .40 S&W presents some practical challenges:
- Increased Recoil: .40 S&W is known for its snappy recoil, making it less comfortable to shoot, especially for beginners. This increased recoil can also impact accuracy.
- Reliability Issues: Even with a properly installed conversion kit, there's a higher chance of malfunctions compared to using the firearm in its original 9mm configuration. This can be due to variations in component tolerances.
- Cost: A conversion kit represents a significant investment, often a substantial portion of the cost of a dedicated .40 S&W Glock.
- Maintenance: Switching between calibers requires careful cleaning and maintenance to ensure reliable operation.
Alternatives to Conversion Kits
Before investing in a conversion kit, consider these alternatives:
- Purchasing a Dedicated .40 S&W Glock: This is often the most reliable and cost-effective solution in the long run. It eliminates the potential for issues stemming from conversion kits.
- Sticking with 9mm: The 9mm Parabellum offers a good balance of stopping power, capacity, and manageable recoil, making it a highly versatile and popular cartridge.
Conclusion: Proceed with Caution
A Glock 17 .40 S&W conversion kit can be tempting, but it's not a simple or always reliable solution. The increased recoil, potential reliability issues, and the cost involved should be carefully weighed against the benefits. In many cases, purchasing a dedicated .40 S&W firearm or sticking with the 9mm configuration might be the more practical and safer choice. Always prioritize firearm safety and proper maintenance, regardless of your chosen caliber. Remember to consult with experienced gunsmiths and thoroughly research the specific kit before installation.
