Understanding the Transformation
The Glock 23, a stalwart of law enforcement and civilian personal defense, is renowned for its reliability and chambering in the potent .40 Smith & Wesson cartridge. But for some, the allure of a Glock can be enhanced by adapting it to a different caliber, specifically, 9mm. This guide provides a comprehensive look at the Glock 23 9mm Conversion Gen 3, detailing everything you need to know about transforming your trusted sidearm. We’ll delve into the components required, the conversion process, potential benefits, and important considerations to ensure a safe and successful transition.
The original Glock 23, as previously mentioned, is built around the .40 S&W round, a cartridge known for its stopping power and the associated recoil. Changing to 9mm changes the fundamentals of the pistol’s operation. This change provides options that go beyond just saving some money.
The basic process involves replacing parts that interact directly with the ammunition. The most critical element is the barrel. Since the 9mm round is of a different diameter than the .40 S&W, a 9mm barrel is necessary for the conversion to function correctly. The 9mm cartridge is typically considered a more economic choice than the .40 S&W and is significantly more available in many locations. In addition to cost, the reduced recoil associated with 9mm can lead to faster follow-up shots and improved accuracy for some shooters.
Essential Components for the Conversion
Success in the world of Glock 23 9mm Conversion Gen 3 hinges on assembling the right components. Let’s explore the vital elements involved:
The Heart of the Matter: The Barrel
At the very core of the transformation is the barrel. A conversion barrel is specifically engineered to chamber and fire the 9mm round within the Glock 23’s slide. The correct barrel will fit snugly and provide the correct dimensions for proper function. You have choices. The most common type are aftermarket conversion barrels, produced by specialist manufacturers. These come in different materials, finishes, and features.
When selecting a conversion barrel, consider the material. Barrels are typically made from stainless steel or carbon steel, each with advantages. Stainless steel offers excellent corrosion resistance, while carbon steel barrels often provide a lower cost. The rifling type, which determines the spin imparted to the bullet, also plays a role. Many barrels utilize traditional land-and-groove rifling, while others incorporate polygonal rifling, similar to what Glock uses in its factory barrels. Each style has its proponents and detractors. Look for reputable brands and reviews to help guide your choice.
The Magazine is Key
The original .40 S&W magazines will not function properly with 9mm ammunition. Therefore, replacing them with 9mm magazines is absolutely necessary. The dimensions and feed lips of a .40 S&W magazine are designed to hold and feed a different cartridge, making them incompatible.
9mm magazines are readily available from a variety of manufacturers, including Glock itself and aftermarket suppliers. It’s generally a good idea to purchase magazines from established brands. These tend to offer better reliability and manufacturing standards. Consider your needs. Do you require magazines for range use, concealed carry, or home defense? The magazine capacity and build (for example, if it has extended basepads) could influence your selection. Having several magazines at your disposal is always a wise idea, as this facilitates quicker reloads.
Recoil Spring Assembly? Potentially.
The recoil spring assembly is a component that, depending on the specifics of your setup and ammunition, may or may not need to be replaced. Some shooters report no issues using the .40 S&W recoil spring with 9mm. However, some sources say the reduced recoil impulse of the 9mm might require a lighter recoil spring to optimize cycling. The general rule of thumb would be to test your setup.
The weight of the spring may impact the cycling reliability of your pistol, especially with different grain ammunition. A spring that is too heavy may lead to failures to feed, while a spring that is too light can cause failures to eject. Experiment and test.
Other Potential Modifications
While the barrel and magazines are the essential elements, certain other parts can be upgraded as well. The ejector, which removes the spent casing from the firearm after firing, may sometimes benefit from replacement, though it’s often unnecessary. Similarly, some choose to switch slides. The slide is the upper portion of the pistol where the barrel is housed. Changing the slide itself is considered an extreme measure, and not often required.
The Conversion Process: A Step-by-Step Guide
Before diving into any mechanical work, safety is the paramount concern.
Safety First
- Verify the firearm is unloaded: This is non-negotiable.
- Clear the firearm: Pull the slide back and physically inspect the chamber to ensure it’s empty. Then, visually inspect the magazine well.
- Point the muzzle in a safe direction: Always direct the barrel toward a safe area where accidental discharge will not cause injury or damage.
- Use proper eye protection: Safety glasses or similar eyewear should be worn throughout the entire process to shield your eyes from potential debris.
- Read and understand your firearm’s manual: Familiarize yourself with the manufacturer’s instructions and safety protocols.
Disassembly of the Glock 23 Slide
- Remove the slide from the frame: Remove the magazine and pull the slide to the rear. Pull down on the takedown levers on both sides of the frame, the slide should then be able to be removed from the frame.
- Remove the recoil spring assembly: Depress the recoil spring guide rod from the front and remove it from the slide.
- Remove the striker assembly: This is often done by using a punch to push out a small pin at the rear of the slide. The backplate and striker assembly will slide out.
- Remove the extractor and its components: Carefully remove the extractor and its associated parts, as it’s generally designed for the .40 S&W cartridge.
- Remove the original barrel: Push the barrel forward and lift it out of the slide.
Installing the 9mm Components
- Install the new barrel: Carefully insert the 9mm conversion barrel into the slide, ensuring it fits properly.
- Reassemble the slide: Install all the previously removed components in reverse order. The recoil spring assembly, striker assembly, and extractor are reinstalled.
- Confirm that the slide moves smoothly: Manually cycle the slide several times to ensure everything functions properly and the barrel is properly seated.
- Attach the slide to the frame: Reattach the slide to the frame by pulling the slide back and pushing the takedown levers back up to their locked position.
Magazine Swap
- Insert your new 9mm magazine into the Glock frame.
- Ensure the magazine locks securely into place.
Testing and Troubleshooting
Once the conversion is complete, the real test begins.
Function Check
- Manual Cycling: Manually cycle the slide repeatedly. Watch and listen to ensure the slide moves smoothly, the extractor consistently engages the case rim, and the slide locks back on an empty magazine.
- Dry Fire: Perform dry fire to confirm the firing pin is hitting the primer.
Live Fire Testing
- Range Time: Go to the range.
- Initial Rounds: Load a few rounds into the magazine.
- Observe Function: Fire the first few rounds and pay close attention. Does it feed, fire, and eject properly?
Common Issues and Solutions
