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 competition, duty carry, or range use.
Is this a genuine CZ magazine or aftermarket?
The magazine body is a genuine CZ OEM factory magazine with the distinctive orange follower—identical to the magazines that ship with new CZ pistols from the factory. The extension is manufactured by Shield Arms and professionally installed on the CZ magazine body. This combination delivers OEM magazine reliability with Shield Arms extended capacity engineering.
Will this work in my CZ P09 as well?
Yes! The CZ P10F and P09 use the same magazine body design, so this pre-installed magazine works perfectly in both full-size pistols. One magazine serves both platforms if you own multiple CZ full-size models.
Is 24 rounds legal for USPSA Limited division?
Yes, USPSA Limited division typically allows extended capacity magazines without restriction. This 24-round configuration is widely used in Limited division competition. Always verify current division rules before matches, as rules can be updated.
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 P10F or P09 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 competition stages, duty carry, or range training. There's no installation, setup, or break-in period required.
Can I disassemble this magazine for cleaning between matches?
Yes, the unique easy-access floor plate design allows you to service and clean the magazine body without removing the extension. This is especially valuable for competitive shooters who clean magazines between major matches or high-volume trainers who perform regular maintenance.
Is the enhanced spring necessary for reliability with 24 rounds?
Absolutely. The included +10% power spring is specifically engineered to ensure reliable feeding across all 24 rounds. Extended capacity magazines require significantly more spring compression, and the enhanced spring maintains proper tension throughout the entire capacity range for consistent, match-grade performance.
Are there magazine capacity restrictions I should know about?
Magazine capacity laws vary significantly by jurisdiction. Some states 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'm building a complete competition magazine set?
This pre-installed option is ideal for building your competition magazine inventory. Order multiple magazines to create a complete match-ready rotation. Each magazine arrives professionally assembled and tested, saving significant time when building a set of 8-12 magazines for major matches.
