Frequently Asked Questions
Will this extension work with both my CZ P10C and P07?
Yes, this extension is designed to work with both CZ P10C Compact and CZ P07 Duty pistols. Both models use compatible magazine bodies, so one extension works for both firearms.

How many rounds does this add to my magazine?
The extension adds 5 additional rounds to 9mm magazines (bringing standard 15-round magazines to 20 rounds total) or 4 additional rounds to .40 S&W magazines (bringing 12-round magazines to 16 rounds total).

Does this require any permanent modifications to my magazines?
No, this is a drop-in installation that requires no permanent modifications. You can easily remove the extension and return your magazine to factory configuration if desired.

Will this extension affect magazine reliability?
No, the Shield Arms extension is precision-engineered to maintain factory magazine reliability. The extension uses CZ OEM springs and followers to ensure consistent feeding and operation. Thousands of competitive shooters trust these extensions for match use where reliability is critical.

Is installation difficult? What tools do I need?
Installation is straightforward and takes just a few minutes. All necessary hardware and allen wrenches are included with your extension. For detailed step-by-step instructions, visit our installation guides page.

Can I use this extension for concealed carry?
While you can use this extension for concealed carry, the added length may make concealment more challenging depending on your carry method and body type. Many users prefer standard capacity magazines for carry and save extended magazines for competition or range use.

Are these extensions legal in all states?
Magazine capacity laws vary by state and locality. Some jurisdictions restrict magazine capacity to 10 rounds or less. It is your responsibility to ensure compliance with all applicable federal, state, and local laws. Shield Arms is not responsible for ensuring compliance with your local regulations.

What's the difference between aluminum and polymer extensions?
Aluminum extensions offer superior durability and impact resistance compared to polymer alternatives. They're less likely to crack from drops or sustained use, and they maintain tighter dimensional tolerances over time. While slightly heavier than polymer, aluminum extensions provide professional-grade durability for serious users.

Will this work with aftermarket magazines?
This extension is designed specifically for CZ OEM factory magazines. While it may work with some aftermarket magazines, we cannot guarantee fitment or function with non-OEM products. For best results, use with CZ factory magazines.

What's covered under the warranty?
Shield Arms provides a 100% lifetime warranty covering manufacturing defects and material failures. Additionally, our "Spring for Life" guarantee means we'll replace your magazine spring free of charge if it ever wears out or loses tension.

Can I get this extension pre-installed on a magazine?
Yes! We offer the CZ P10C +5 Pre-Installed 9mm Magazine Extension, which includes a complete magazine with the extension already installed and tested—ready to use right out of the package.
