3 Best Glock Magazine Extensions and Accessories
With incredible performance, easy maintainability, and unbeatable reliability, Glocks are the most popular handgun in the world for a reason. But these guns aren’t just expertly crafted firearms. Glocks feature a modular design that allows Glock owners to not only replace broken parts with new ones, but also swap them out for aftermarket parts. One of the easiest and most popular parts to swap out is the base plate for a magazine extension or accessory. They can do a variety of things from adding weight to giving you some extra rounds. And if you’re someone who carries their Glock as a CCW, those extra rounds can mean the difference between life and death in the moment you need them most.
But with so many Glock base plates on the market, where do you start? Well, that’s where we come in. Let’s talk about what an extended magazine is, why you would want one, and more to help you choose the best Glock magazine extension for you.
What is an extended magazine?
An extended magazine is exactly what it sounds like: an add-on to your magazine to extend it. While many people use “extended magazine” to refer to a magazine with an increased round capacity, it actually applies to all Glock mag extensions, even ones that don’t have anything to do with ammo. These extensions range from adding weight for better stabilization to window smashers that help you escape from a car wreck.
So what are some of these base plates? Let’s dive into our list of the best Glock magazine extensions and accessories for your firearm.
1. +5 Capacity Magazine Extension

A +5 capacity magazine extension increases your mag’s capacity by five rounds. Plus, they give you a little extra room on the grip for another finger, improving your control over your gun.
More rounds in your magazine means less frequent reloading. If you’re a competitive shooter who wants to cut down on their course run times, this is the best Glock magazine extension for reducing time lost reloading. It can also be crucial for CCW holders in a moment of dire need.
2. Weighted Mag Plates

A heavier gun is easier to control. A quick way to add more weight is to just, well, add a weight. A Glock weighted base plate is a small block of stainless steel that replaces the base plate at the bottom of the mag. The added weight keeps your gun stable with repeat shots, as well as provides extra room for shooters with larger hands to grip.
The result is the best Glock magazine extension accessory for improving your accuracy and control over your firearm. If you’re a competitive shooter who wants to improve your precision, an everyday carrier who can’t afford to miss a shot, or just a guy who loves range days, this is the extension to go for.
Window Breaker Base Plates
Most magazine accessories help improve the performance of your gun. However, very few expand their functionality. By swapping your factory base plate with a window breaker tool, your Glock isn’t just a weapon in a crisis. It’s a tool, too — and, even better, it’s a tool for smashing things.
Whether you’re breaking out of a wrecked car or smashing windows during an evacuation, a window smasher is the best Glock magazine extension accessory for you. Plus, the heft it adds to your gun helps steady it with repeat shots, improving your accuracy. It may not add round capacity to your gun or be as heavy as weighted base plates, but the versatility of these base plates is unmatched.
