The Shield Arms CZ P10-C/P07 magazine extension is a precision-engineered capacity booster for shooters running either the compact or full-size CZ platform. Whether you're training, competing, or carrying, this aluminum extension adds 5 rounds of 9mm or 4 rounds of .40 S&W to your existing OEM magazines—without sacrificing reliability or ergonomics. It's the kind of straightforward upgrade that lets you carry more ammunition and reload less often, all while maintaining the clean lines and handling of your CZ.
Machined from billet 6061 aluminum and finished with Type 2 anodize, this extension is built to last. The real-world design detail here is the easy-access floor plate: you can service the magazine, clean the spring and follower, and perform maintenance without ever separating the extension from the magazine body. That means faster field cleaning and less time fussing with small parts. The index cuts machined into the body give you positive grip when stripping magazines from a pouch, and it plays well with most aftermarket flared mag wells if you've upgraded your grip.
Shield Arms includes a high-power spring engineered to handle the extra capacity, and backs the extension with their lifetime warranty and Spring for Life guarantee. Made in the USA, it's engineered for the new-style P10-C and P07 magazines with the orange follower—verify your magazine generation before ordering. Whether you're building out a defensive pistol, rounding out a competition load-out, or just want deeper mags for the range, this extension delivers function and durability in a no-nonsense package.
