The Essential Buying Guide for Your Glock 19 Magazine Extension

Adding a magazine extension to your Glock 19 is a smart move. It gives your trusty handgun more bullets, making it ready for more shooting practice or self-defense situations. But choosing the right one can feel tricky. This guide helps you pick the best extension for your needs.

Key Features to Look For

When shopping for a Glock 19 mag extension, focus on these important parts:

  • Capacity Boost: How many extra rounds does it add? Most popular extensions add +2, +3, or even +5 rounds. Decide how much extra firepower you need.
  • Locking Mechanism: How securely does the extension attach to your factory magazine? A strong, reliable lock prevents the extension from falling off under stress.
  • Grip Surface: Does the extension add helpful texture or shape? A good extension should feel comfortable in your hand and make gripping the magazine easier for fast reloads.
  • Ease of Installation: Can you put it on and take it off without special tools? Simple installation is always better for most users.

Important Materials Matter

The material used directly affects how long your extension lasts and how reliable it is.

Polymer vs. Metal
  • High-Quality Polymer: Most top extensions use tough, durable polymer (like the material Glock uses for its frames). This keeps the weight down and resists scratches well.
  • Aluminum or Steel: Some premium extensions use metal. Metal offers extreme durability but adds noticeable weight to your loaded magazine.

For everyday carry (EDC) or range use, strong polymer usually offers the best balance of toughness and weight.

Factors That Improve or Reduce Quality

Quality isn’t just about the brand name. Look closely at these details:

What Makes It Better?
  • Tight Tolerances: Quality extensions fit snugly onto the magazine. Loose parts rattle or might detach under hard use.
  • Spring Quality: The extension needs a strong, reliable magazine spring to push the extra rounds up correctly every time.
  • Finish Quality: A good finish resists chipping and fading, keeping your setup looking sharp.
What Lowers the Quality?
  • Cheap Plastic: Very cheap plastic can crack if dropped on concrete.
  • Poor Fit: If the extension wobbles even slightly, it’s a sign of low-quality manufacturing.

User Experience and Use Cases

Think about why you are adding the extension. This helps narrow down your choices.

Range Days vs. Self-Defense
  • Range Use: If you only shoot at the range, you might choose a larger, heavier extension (+5) for maximum capacity. Weight isn’t a big concern here.
  • Concealed Carry (EDC): If you carry concealed, you probably want a smaller, lighter +2 extension. These add capacity without making the grip too long to hide easily.

Most users find that a +2 extension provides a great grip improvement while keeping the overall profile manageable. Always test your chosen extension thoroughly at the range before trusting it for defense.


10 Frequently Asked Questions (FAQ) About Glock 19 Mag Extensions

Q: Will a Glock 19 extension fit a Glock 17 magazine?

A: No, generally they are not cross-compatible. Glock 19 extensions are designed specifically for the shorter G19 frame and magazine length.

Q: Are magazine extensions legal everywhere?

A: This depends entirely on your local and state laws. Some areas restrict magazine capacity, which indirectly limits the size of the extension you can use.

Q: Do I need a new, longer spring when I add an extension?

A: Some +3 or +5 extensions come with a new, stronger spring. For simple +2 extensions, the factory spring often works fine, but checking the manufacturer’s instructions is important.

Q: How do I clean the magazine after adding an extension?

A: You usually need to detach the extension first. Once detached, you clean the magazine body and the extension separately, just like a normal magazine.

Q: Does adding an extension make reloading slower?

A: For many shooters, a well-designed extension actually makes reloading faster. The added surface area helps you grab the magazine quickly.

Q: What is the most common capacity increase?

A: The +2 extension is the most popular choice for Glock 19 owners who carry concealed.

Q: Can I use a G19 extension on a G23 (.40 S&W)?

A: Extensions are usually caliber-specific. Do not mix parts between the 9mm (G19) and .40 S&W (G23) magazines.

Q: Will the extension affect feeding reliability?

A: A high-quality, properly installed extension should not affect reliability. A poorly made or incorrectly installed one can cause feeding failures.

Q: Are extended baseplates always made by Glock?

A: No. Many excellent third-party companies make these parts, often offering better features or materials than standard factory accessories.

Q: How much weight does a +2 extension add?

A: A polymer +2 extension usually adds very little weight, often less than one ounce when empty.
