Frequently Asked Questions
What's included with this pre-installed magazine?
You receive a complete, ready-to-use magazine including: a genuine CZ OEM magazine body with orange follower, Shield Arms +5 aluminum extension pre-installed, enhanced +10% power spring, and professional assembly that's been function-tested before shipping. Simply load it with ammunition and it's ready for carry or competition.
Is this a genuine CZ magazine or aftermarket?
The magazine body is a genuine CZ OEM factory magazine with the distinctive orange follower—the same magazine that ships with new CZ pistols. The extension is manufactured by Shield Arms and professionally installed on the CZ magazine body. This combination gives you OEM magazine reliability with Shield Arms extended capacity engineering.
Will this work in my CZ P07 as well?
Yes! The CZ P10C and P07 use the same magazine body, so this pre-installed magazine works perfectly in both pistols. One magazine serves both platforms if you own multiple CZ compact models.
How is this different from buying the extension separately?
The pre-installed option includes the complete CZ OEM magazine body, enhanced +10% power spring, and professional installation with function testing—all ready to use immediately. The extension-only option is for users who already own CZ P10C or P07 magazines and want to install the extensions themselves.
Do I need to do any assembly or installation?
No, this magazine arrives completely assembled, professionally installed, tested, and ready to use. Simply load it with ammunition and it's ready for carry, competition, or range use. There's no installation or setup required.
Can I disassemble this magazine for cleaning?
Yes, the unique easy-access floor plate design allows you to service and clean the magazine body without removing the extension. This makes routine maintenance simple while preserving the integrity of the extension installation—especially useful for competitive shooters or high-volume trainers.
Is 20 rounds enough for USPSA Production division?
USPSA Production division has specific magazine capacity limits that can vary. Always verify current division rules before competition. This 20-round configuration is widely used in Carry Optics division and other divisions where capacity is unrestricted or has higher limits.
Is the enhanced spring necessary for reliability?
Yes, the included +10% power spring is specifically selected to ensure reliable feeding across all 20 rounds. Extended capacity magazines require more spring compression, and the enhanced spring maintains proper tension throughout the entire capacity range for consistent, reliable performance under all conditions.
Are there magazine capacity restrictions I should know about?
Magazine capacity laws vary significantly by jurisdiction. Some states and localities restrict magazines to 10 or 15 rounds, while others have different limits. It is your sole responsibility to ensure compliance with all applicable federal, state, and local laws. Shield Arms cannot provide legal advice regarding your specific location.
What if I want to build multiple extended magazines?
This pre-installed option is perfect for building your magazine inventory. Order multiple magazines to create a complete rotation for carry, competition, or training. Each magazine arrives ready to use, saving significant installation time when building your collection of extended capacity magazines.
