Description
If you run a CZ 75, you're already working with a solid platform. This Warne magazine extension takes that reliability and gives you more rounds without compromising the gun's balance or feel. It's not just added capacity though, it's about improving how your magazines work in your hands.
Warne machined this extension from 6061 T6 aluminum billet and applied a Type II hardcoat anodize finish, which means it can handle regular use without showing wear. The finish protects against corrosion and maintains that clean black look shot after shot. What makes it practical is the finger grooves machined into the body. These aren't cosmetic, they actually give you better purchase when you're pulling the magazine from the gun or doing tactical reloads under pressure.
Installation and Retention
The extension stays put with a Torx head screw and washer, so installation is straightforward and doesn't require any permanent modifications. You remove the factory basepad, install the extension, and secure it with the screw. No gunsmithing needed. The whole process takes minutes if you're comfortable working with your own magazines.
Capacity and Competition Ready
This adds four rounds to your factory 17-round CZ 75 magazines, and it's designed to work with standard CZ 75 factory mags. The extension meets USPSA 141.25mm legal length specifications, so it works for competitive shooting without worrying about regulations. Whether you're at the range or preparing for precision shooting sports, you get the extra rounds you want without any hassle.

Frequently Asked Questions
Will this work with other CZ models or just the CZ 75?
This extension is designed specifically for CZ 75 factory 17-round magazines. Warne makes extensions for other CZ models like the P-07 and P-09, but you need to match the specific model to the magazine. If you have a different CZ platform, check the product specifications before ordering to make sure it's the right fit for your gun.
Do I need a new magazine spring when installing this extension?
Some Warne extensions come with a replacement spring, and some don't. Check your product packaging to see what you received. If yours included a new spring, follow the installation instructions to swap the follower from the factory spring to the new one. If there's no replacement spring included, your factory spring may work fine, but always test function before relying on the magazine.
Does the extension stay secure with just the Torx screw?
Yes. The Torx head screw and washer are designed to securely retain the extension to the magazine body. Once installed and tightened, it stays put through regular use. Make sure you tighten it firmly during installation, and you won't have issues with it coming loose.
Can I use this extension in USPSA competition?
Yes. This extension meets USPSA 141.25mm legal length specifications, so it's approved for USPSA competition. It gives you four extra rounds while staying within the gauge requirement, which makes it a practical choice if you compete in limited or open division.
