Frequently Asked Questions
What's the difference between this and the extension-only product?
The pre-installed version includes a complete OEM Springfield Echelon 17-round magazine with the Shield Arms +5 extension already professionally installed, tested, and ready to use. The extension-only product is just the extension component, which you install on your existing magazines. Choose pre-installed if you want to add magazines to your collection or prefer professional assembly. Choose extension-only if you want to upgrade magazines you already own.
Is this a genuine Springfield magazine?
Yes. Each pre-installed magazine uses an authentic OEM Springfield Echelon 17-round magazine as the base. We source genuine factory magazines and professionally install our Shield Arms +5 extension to create a complete 22-round solution. You receive the same high-quality magazine that ships with your Springfield Echelon, enhanced with our innovative extension technology.
Do I need to do any assembly or installation?
No. The magazine arrives completely assembled, professionally installed, and function-tested. Simply load it with ammunition and it's ready to use. There's no assembly, no installation, and no tools required. This is the ultimate convenience for shooters who want maximum capacity with zero setup time.
Will this work in my Springfield Echelon?
Yes. This magazine is compatible with all Springfield Echelon variants. Since it uses a genuine OEM Springfield Echelon magazine as the base, compatibility is guaranteed. The extension adds five additional rounds while maintaining reliable feeding and function in your Echelon pistol.
Is this magazine USPSA legal for competition?
Yes. The assembled magazine has an overall length of 141.25mm, which meets USPSA division requirements. The 22-round total capacity is compliant for divisions that allow magazine extensions. Always verify current competition rules for your specific division, as regulations can change. Many competitors use these magazines successfully in USPSA and IPSC matches.
How do I maintain the magazine?
The easy-access floor plate design makes maintenance simple. Unlike traditional extensions that require complete disassembly, you can access the spring and follower without removing the extension from the magazine body. This allows for quick cleaning, inspection, and spring service. Detailed maintenance instructions are included with your magazine.
Can I use this for concealed carry or duty use?
Yes. Many law enforcement professionals and concealed carriers use these extended magazines for duty or defensive applications. The additional five rounds provide enhanced capacity for critical situations. However, always verify that the extended magazine fits properly in your holster and magazine pouches before relying on it for carry purposes. Some agencies may have specific policies regarding magazine modifications or extended magazines.
Has this magazine been tested for reliability?
Yes. Every pre-installed magazine undergoes professional function testing before shipping. Our technicians verify smooth feeding, proper follower operation, and reliable performance under spring tension. This quality assurance process ensures you receive a magazine that performs flawlessly from the first round. The combination of OEM magazine quality and professional assembly delivers proven reliability.
How many of these magazines should I buy?
Most competition shooters carry 4-6 magazines for match day, while recreational shooters typically have 3-4 magazines for range sessions. For duty or defensive use, consider having at least 2-3 magazines as part of your loadout. Additional magazines reduce loading time at the range and provide backup options during competition or training. Many customers purchase multiple pre-installed magazines to build a complete magazine collection immediately.
What warranty coverage does this include?
The complete magazine assembly is covered by Shield Arms' 100% lifetime warranty against defects in materials and workmanship. Additionally, the magazine is protected by our Spring for Life guarantee, which ensures your magazine spring performs reliably for the life of your firearm. This comprehensive warranty coverage demonstrates our confidence in both the OEM magazine quality and our professional assembly process.
Can I remove the extension if I want to return to standard capacity?
While the extension can technically be removed, these magazines are sold as complete pre-installed units. If you anticipate needing both extended and standard-capacity configurations, we recommend keeping your original factory magazines for standard use and using these pre-installed magazines for extended capacity applications. This approach ensures you have the right magazine for any situation.
Is the aluminum extension durable enough for hard use?
Absolutely. The Shield Arms extension is CNC-machined from billet 6061 aluminum—a aerospace-grade material known for exceptional strength and durability—and features a Type 2 anodized finish for corrosion resistance. This construction provides superior impact resistance compared to polymer base plates while maintaining reasonable weight. The extension is designed to withstand the rigors of competition, training, and professional use, backed by our lifetime warranty.
