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 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 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.
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 P10S magazines and want to install the extensions themselves.
Do I need to do any assembly or installation?
No, this magazine arrives completely assembled, tested, and ready to use. Simply load it with ammunition and it's ready for carry, competition, or range use. There's no installation 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.
Will this work in my P10C or P07?
No, this magazine is designed specifically for the CZ P10S subcompact model only. The P10S has unique magazine dimensions. For P10C or P07 pistols, check out our CZ P10C +5 Pre-Installed Magazine.
Is the enhanced spring necessary for reliability?
The included +10% power spring is specifically selected to ensure reliable feeding across all 15 rounds. Extended capacity magazines require more spring compression, and the enhanced spring maintains proper tension throughout the entire capacity range for consistent performance.
How much does this add to my concealed carry setup?
The extension adds approximately one inch to your magazine length while adding 5 critical rounds. For most concealed carriers, this is a worthwhile trade-off—you maintain your P10S's compact grip length while gaining 50% more capacity. Many appendix and strong-side IWB carriers find the extension barely noticeable.
Can I use this magazine for daily carry?
Absolutely. This magazine is ideal for concealed carry. The aluminum construction provides excellent durability for daily carry conditions, the enhanced spring ensures reliable feeding, and the pre-installed assembly has been factory tested. Thousands of P10S carriers trust this configuration for daily concealed carry.
What makes this better than other extended magazines?
This uses a genuine CZ OEM magazine body (not aftermarket), features precision-machined aluminum construction (not polymer), includes an enhanced power spring, and most importantly—arrives professionally assembled and function-tested. You get OEM reliability with extended capacity, ready to use immediately.
Are there magazine capacity restrictions I should know about?
Magazine capacity laws vary significantly by jurisdiction. Some states and localities restrict magazines to 10 rounds or less. 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 installation time when building your collection.
