Fitting a full-size Glock 17 magazine into a Glock 19 is a common modification sought by shooters. The longer 17-round magazine offers increased capacity, a significant advantage in certain situations. However, directly inserting a Glock 17 magazine into a Glock 19's grip results in an incomplete fit and potential malfunctions. This is where magazine spacers come in. This guide will explore the use of spacers, the benefits and drawbacks, and important considerations before attempting this modification.
Understanding the Compatibility Issue
The core difference lies in the magazine well's dimensions. The Glock 19, being a compact model, has a shorter grip and magazine well compared to the full-size Glock 17. This size discrepancy prevents the longer 17-round magazine from seating properly. The baseplate of the 17-round magazine will typically protrude from the bottom of the 19's grip.
The Role of Magazine Spacers
Magazine spacers are designed to bridge this gap. They are typically small, polymer inserts that fit inside the Glock 19's magazine well. The spacer takes up the extra space, allowing the Glock 17 magazine to seat completely and function correctly. This ensures a stable and reliable platform for the magazine, preventing potential issues during shooting.
Benefits of Using a Glock 19 Spacer with a Glock 17 Magazine
-
Increased Capacity: The most significant benefit is the obvious jump in ammunition capacity. Carrying an extra 6-7 rounds (depending on the magazine type) can be a considerable advantage in self-defense or competitive shooting scenarios.
-
Improved Ergonomics (Potentially): For some shooters, the added length provided by the Glock 17 magazine in the Glock 19, when used with a spacer, can improve grip and overall comfort. This is subjective and depends on individual hand size and shooting style.
-
Cost-Effective Modification: Compared to other modifications or purchasing a completely different firearm, using a spacer is a relatively inexpensive solution to increase magazine capacity.
Drawbacks and Considerations
-
Potential for Malfunction: While spacers generally improve reliability, improper installation or low-quality spacers can lead to feeding issues or magazine drops. It's crucial to select high-quality spacers from reputable manufacturers.
-
Altered Ergonomics (Potentially): For some shooters, the extended grip can feel awkward or uncomfortable. This is especially true if the spacer isn't correctly installed or if the shooter has smaller hands.
-
Legal Implications: Check local and state laws regarding magazine capacity. Some jurisdictions have strict regulations on magazine size.
Choosing and Installing a Spacer
When selecting a spacer, ensure it's specifically designed for Glock 19 and Glock 17 magazine compatibility. Look for reviews and recommendations from trusted sources.
Installation is usually straightforward; however, always consult the manufacturer's instructions. Improper installation can damage your firearm or the spacer itself.
Conclusion
Using a Glock 19 spacer with a Glock 17 magazine offers a viable path to increase carrying capacity. However, careful consideration of the potential drawbacks and a thorough understanding of installation are crucial for safe and reliable performance. Always prioritize firearm safety and responsible gun ownership. Choose high-quality products and practice regularly to ensure proficiency with your modified firearm.
