Increase Your Capacity and Lethality with a Glock Magazine Extension

A mag extension is one of the most popular customizations for pistol shooters—concealed carry, home defense, and other applications certainly warrant extended capacity.

In this guide, we’re breaking down why you should consider adding a mag extension to your Glock and noting some of the best Glock magazine extensions on the market today. But the best choice is the one that offers the perfect balance of grip support, increased capacity, and (if applicable) concealability.

Why Add a Mag Extension to Your Glock?

There are two main reasons why shooters may consider customizing their Glock magazines with extensions:

  1. Increased capacity – Simply put, more rounds equals more chances to neutralize your target. In a concealed carry or home defense scenario, every opportunity counts—why not increase your odds by adding more rounds?
  2. Increased comfort – For shooters with larger hands looking to shoot a compact or subcompact pistol, limited grip space can compromise comfort and (more importantly) a stable, confident hold on your gun. Mag extensions also offer a grip extension opportunity to increase potential handhold space.

What is the Best Glock Magazine Extension?

The best Glock magazine extension is one that offers the shooter the right balance of three elements:

  1. Boosted capacity
  2. Grip comfort
  3. Concealability (if applicable)

In addition, Glocksmiths should only consider products that meet the criteria of their jurisdiction’s magazine capacity regulations.

Here are some product highlights from MILSPIN’s collection of high-quality, American-made mag extensions:
