The Glock 23, a compact .40 S&W pistol, offers a robust platform for concealed carry. However, the rising popularity and cost-effectiveness of 9mm ammunition have many owners considering a conversion. This comprehensive guide explores the various methods for converting your Glock 23 to 9mm, weighing the pros and cons of each approach.
Understanding the Conversion Options
Converting your Glock 23 to 9mm isn't a simple barrel swap. The .40 S&W and 9mm cartridges have different dimensions, requiring more significant modifications for reliable function. Your primary options include:
1. 9mm Conversion Barrels: The Simplest Solution
This is the most straightforward method. Several manufacturers offer 9mm conversion barrels specifically designed for the Glock 23. These barrels replace the original .40 S&W barrel, allowing you to shoot 9mm ammunition.
Pros:
- Cost-effective: Generally the least expensive option.
- Easy Installation: Usually a simple swap, requiring no gunsmithing expertise.
- Reversible: You can easily switch back to the original .40 S&W barrel.
Cons:
- Potential for Reliability Issues: While many work flawlessly, some users report malfunctions like stovepipes or failures to feed, especially with certain ammunition types.
- Limited Availability of High-Quality Options: Not all conversion barrels are created equal; research is crucial to find a reputable brand.
- Magazine Compatibility: You might need 9mm Glock magazines (e.g., Glock 19 magazines) which adds to the overall cost.
2. Complete 9mm Slide Assembly: A More Robust Solution
This option involves replacing the entire slide assembly with one designed for 9mm. This includes the slide, barrel, and other components.
Pros:
- Improved Reliability: A complete 9mm slide assembly is typically more reliable than just a conversion barrel. The parts are designed to work together optimally.
- Enhanced Performance: Often offers improved accuracy and reduced recoil compared to a simple barrel conversion.
Cons:
- Higher Cost: Significantly more expensive than a simple barrel conversion.
- Requires More Research: Ensure compatibility with your existing Glock 23 frame. Some aftermarket slides might not be compatible.
- Less Reversible: Switching back to the original .40 S&W setup involves reinstalling the original slide assembly.
3. Professional Gunsmithing: The Custom Approach
For the most reliable and potentially customized conversion, consider a professional gunsmith. A skilled gunsmith can modify your existing Glock 23 frame and slide to accommodate a 9mm barrel and other necessary components.
Pros:
- Highest Reliability: Offers the greatest chance of flawless performance.
- Potential for Customization: Allows for additional modifications, like trigger work or upgraded components.
- Warranty and Support: A reputable gunsmith will typically provide a warranty on their work.
Cons:
- Most Expensive Option: Expect to pay a premium for professional gunsmithing services.
- Time-Consuming: The process may take several weeks or even months.
Choosing the Right Conversion Method
The best conversion method depends on your budget, technical skills, and desired level of reliability. If you're on a budget and comfortable with minor gun maintenance, a 9mm conversion barrel might suffice. For optimal performance and reliability, a complete 9mm slide assembly or professional gunsmithing is the preferred route.
Remember always to prioritize safety. If you're not comfortable performing the conversion yourself, seek the services of a qualified and reputable gunsmith. Properly follow all safety guidelines and ensure your firearm is functioning correctly before carrying or using it. Improper conversions can lead to malfunction and potential injury.
