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 shooting disciplines or self-defense scenarios. However, directly inserting a Glock 17 magazine into a Glock 19 frame results in an incomplete and unsafe seating. This is where magazine spacers come in. This guide explores the use of spacers, their benefits, drawbacks, and crucial considerations before attempting this modification.
Understanding the Issue: Magazine Compatibility
The fundamental reason a Glock 17 magazine doesn't fit a Glock 19 is the difference in frame size. The Glock 19 has a shorter grip, leaving insufficient space for the longer Glock 17 magazine to fully seat. This results in the magazine baseplate protruding, potentially causing malfunctions during firing, and creating an unstable and unsafe platform.
Magazine Spacers: The Solution
Magazine spacers are specifically designed to bridge this gap. These devices, typically made from polymer or metal, are inserted into the Glock 19 magazine well. They effectively extend the magazine well's length, allowing the longer Glock 17 magazine to seat correctly and securely.
Types of Spacers:
There are several types of Glock 17/19 magazine spacers available, differing primarily in material and design:
-
Polymer Spacers: Generally more affordable and lightweight. They offer good functionality but might wear down over time with extended use.
-
Metal Spacers: Typically more durable and resistant to wear, providing a longer lifespan. However, they often add extra weight to the firearm.
Benefits of Using Spacers:
-
Increased Capacity: The most obvious benefit is the added capacity provided by the Glock 17 magazine (17 rounds versus 15 or 19 rounds depending on the model of Glock 19 magazine).
-
Enhanced Reliability: Correct seating ensures proper magazine function, reducing the risk of malfunctions.
-
Improved Ergonomics (Potentially): For some shooters, the extended grip provided by a Glock 17 magazine with a spacer can enhance their shooting grip and control.
Drawbacks and Considerations:
-
Potential for Malfunctions: While spacers generally improve reliability, incorrect installation or a poorly made spacer can still lead to malfunctions.
-
Added Bulk and Weight: Spacers add length and potentially weight to the firearm, slightly altering its balance and concealability. This is particularly noticeable with metal spacers.
-
Concealability Issues: The increased grip length can make concealed carry more challenging for some individuals.
-
Legality: Always verify the legality of carrying extended magazines in your specific jurisdiction before using a spacer. Magazine capacity restrictions vary widely by location.
Choosing and Installing a Spacer
Selecting a reputable manufacturer is crucial to ensure proper fit and function. Read reviews and compare different spacers before making a purchase. The installation process typically involves simply inserting the spacer into the magazine well. Always refer to the manufacturer's instructions for specific installation guidelines.
Safety First: Thorough Testing
After installing a spacer, rigorously test the firearm's functionality at the range. Fire a significant number of rounds to ensure reliable feeding, ejection, and overall performance. Any sign of malfunction warrants further investigation and potentially removing the spacer.
