Description
If you run a CZ P10C or P07, you're already carrying one of the best platforms out there. The Shield Arms magazine extension takes what you've got and gives you more firepower without making your setup complicated. This adds a true 5 rounds to your 9mm magazines or 4 rounds to .40 S&W, meaning a standard 15-round P10C mag becomes a 20-rounder.
Built for durability and easy maintenance
Machined from 6061 billet aluminum and finished with Type II anodizing, this extension is built to last through training, competition, and carry. The construction is solid enough that it won't wear out or rattle loose after hundreds of reloads. What sets this apart from other extensions is the floor plate design. Instead of having to disassemble the whole thing when you need to clean or maintain your magazine, the floor plate comes off easily, giving you quick access to the spring and follower while the extension stays attached to the mag body. That saves you time and keeps everything organized.
Grip and compatibility
The extension includes machined index cuts that give you better purchase when pulling the magazine from a pouch, making faster reloads easier. It fits standard CZ P10C and P07 magazines with the orange follower and works with most aftermarket flared mag wells, so you can still run your current holster setup. The black finish matches factory CZ magazines, keeping that clean, purposeful look. You get a plus-10 percent power spring included, which ensures reliable feeding without any guesswork.
Warranty and support
Shield Arms backs this with a 100 percent lifetime warranty and their Spring for Life guarantee, which covers any spring issues down the road. Made in the USA, so you're getting quality control and customer support from a company that stands behind their gear.

Frequently Asked Questions
Which CZ magazines work with this extension?
This extension is designed specifically for new-style CZ P10C and P07 magazines that have the orange follower. It won't fit older style magazines or other CZ models. The extension adds 5 rounds to 9mm magazines and 4 rounds to .40 S&W magazines.
Do I need special tools to install the magazine extension?
The extension comes with the tools you need to install it—just a couple of Allen wrenches. Installation involves removing your magazine's factory basepad and spring, sliding the extension onto the mag body, and securing it with a retaining pin. It's straightforward if you follow the steps, though it takes a bit more care than some other extensions.
Can I use this extension with my aftermarket magazine well?
Yes, it's designed to work with most aftermarket flared mag wells that also accept standard CZ P10C and P07 magazines. The extension's beveled edges and index cuts are built with compatibility in mind, but if you're using something unusual, double-check that standard CZ mags fit your setup first.
What's included in the box?
You get the extension itself, an upgraded power spring that's about 10 percent stronger than factory springs, and the small Allen wrenches needed for installation. No magazine is included—you need to have your own CZ P10C or P07 magazines to attach this to.
