The Glock 23, a compact .40 S&W pistol, has earned a reputation for reliability and performance. However, the rising popularity and cost-effectiveness of 9mm ammunition have led many Glock 23 owners to explore conversion options. This comprehensive guide delves into the various methods of converting your Glock 23 to 9mm, weighing the pros and cons of each approach.
Understanding the Glock 23 and 9mm Conversion
The Glock 23's .40 S&W chamber and barrel are not compatible with 9mm ammunition. Attempting to fire 9mm in an unmodified Glock 23 is extremely dangerous and could result in serious injury or damage to the firearm. Therefore, conversion necessitates modification or replacement of key components. The core challenge lies in safely adapting the firearm's dimensions and mechanics to handle the smaller 9mm cartridge.
Why Convert a Glock 23 to 9mm?
Several factors drive the desire to convert a Glock 23 to 9mm:
- Cost Savings: 9mm ammunition is generally cheaper than .40 S&W, allowing for more frequent practice.
- Reduced Recoil: 9mm's lighter recoil makes it more manageable for some shooters, especially those new to firearms.
- Increased Magazine Capacity: 9mm magazines often hold more rounds than comparable .40 S&W magazines.
- Improved Accuracy (Potentially): Some shooters find they achieve better accuracy with 9mm due to the reduced recoil.
Methods for Glock 23 9mm Conversion
There are primarily two approaches to converting your Glock 23 to 9mm:
-
Complete Barrel and Magazine Conversion: This is the most common and generally safest method. It involves replacing the .40 S&W barrel with a 9mm barrel specifically designed for the Glock 23. You will also need 9mm magazines. This is the only method recommended by most gunsmiths and is essential to avoiding the risks inherent in using mismatched parts.
-
Aftermarket Conversion Kits: Some companies offer conversion kits that include the barrel and other necessary parts. While convenient, the quality and reliability of these kits vary significantly. Always ensure the kit is from a reputable manufacturer with good reviews before purchasing.
Detailed Look at Barrel and Magazine Replacement
Replacing the barrel and using a new magazine is the most straightforward and safest way to convert a Glock 23 to 9mm. The process usually involves the following steps:
-
Acquire a 9mm Barrel: Purchase a high-quality 9mm barrel specifically designed for a Glock 23. Avoid cheap or unknown brands. Look for reputable manufacturers such as Lone Wolf Distributors, KKM Precision, or Agency Arms. These barrels are typically drop-in replacements, meaning they don't require extensive gunsmithing.
-
Obtain 9mm Magazines: Get Glock 23 magazines designed for 9mm. These are not interchangeable with the .40 S&W magazines. Again, quality matters, so buy from a reputable source.
-
Installation: The barrel swap itself is usually a relatively simple process, although following instructions carefully is paramount. If you are not comfortable performing this yourself, it is highly recommended that you take it to a licensed gunsmith.
-
Testing: After the conversion, thoroughly test the firearm at a shooting range, using a variety of ammunition to ensure reliability and accuracy.
Important Note: Never attempt to fire your Glock 23 with a 9mm barrel and a .40 S&W magazine or vice versa. This is incredibly dangerous.
Potential Issues with Aftermarket Conversion Kits
While conversion kits offer convenience, they can present challenges:
- Reliability: Some kits may not function reliably, leading to malfunctions like stovepipes, failure to feed, or even dangerous failures to fire.
- Fit and Finish: The quality of the parts in a conversion kit may not be as high as factory components, impacting the overall feel and performance of the pistol.
- Warranty: Using aftermarket parts often voids the manufacturer’s warranty on the firearm.
Safety Precautions
Converting your Glock 23 to 9mm requires careful attention to safety:
- Always follow the manufacturer's instructions: If using a conversion kit, follow its instructions diligently. If replacing just the barrel, ensure you understand the correct disassembly and reassembly procedures for your Glock 23.
- Use only high-quality parts: Cheap or poorly made parts can compromise safety and reliability.
- Thorough testing: After conversion, test the firearm thoroughly at a range, verifying its functionality and accuracy with various types of 9mm ammunition.
- Proper firearm handling: Always practice safe firearm handling techniques.
Conclusion: Weighing the Pros and Cons
Converting a Glock 23 to 9mm offers several advantages, primarily the reduced cost of ammunition and potentially improved shootability. However, it’s crucial to perform the conversion correctly, using high-quality parts and ideally the supervision of a gunsmith if you lack experience. Carefully weigh the benefits against the potential risks before proceeding. Remember, safety should always be your top priority.
