Frequently Asked Questions
Will this extension fit my Springfield Echelon?
Yes, the Shield Arms +5 Magazine Extension is designed specifically for Springfield Echelon pistols. It fits OEM Springfield Echelon 17-round magazines only. All Echelon variants (standard, Compact, etc.) use the same magazine, so this extension is compatible with any Springfield Echelon model that uses the standard 17-round magazine.
Do I need to buy a new spring for this extension?
No. The Shield Arms Echelon +5 Extension is engineered to work with your existing OEM magazine spring. This makes installation simpler and more cost-effective. Simply remove your factory base plate and install the Shield Arms extension using your existing spring—no additional parts required.
What does "easy-access floor plate" mean?
Unlike traditional magazine extensions that require you to completely remove the extension to access the spring and follower, our easy-access floor plate design allows you to service these components without removing the extension from the magazine body. This innovative feature makes cleaning and maintenance significantly faster—especially valuable for competition shooters who need to clean magazines between stages or professionals who maintain equipment regularly.
Is this extension USPSA legal for competition?
Yes. The Shield Arms Echelon +5 Extension has an overall length of 141.25mm, which meets USPSA division requirements. The 22-round total capacity (17+5) is compliant for divisions that allow magazine extensions. Always verify current competition rules for your specific division, as regulations can change.
How difficult is installation?
Installation is straightforward for anyone familiar with basic magazine disassembly. Remove your existing base plate following standard magazine disassembly procedures, then reassemble the magazine with the Shield Arms extension in place of the factory base plate. The process takes just a few minutes and requires no special tools. For detailed step-by-step instructions, visit our installation guides page.
Will this affect magazine reliability?
No. When properly installed, the Shield Arms Echelon +5 Extension maintains or improves feeding reliability. The extension is precisely engineered to work with your existing OEM spring and follower, and the easy-access floor plate design allows for regular maintenance to ensure continued reliable operation. Each extension undergoes function testing before shipment to verify proper operation.
Can I use this for concealed carry or duty use?
Yes. Many law enforcement professionals and concealed carriers use magazine extensions to maximize capacity for duty or defensive applications. The additional five rounds can provide a tactical advantage in critical situations. However, always verify that extended magazines fit properly in your holster and magazine pouches before relying on them for carry purposes. Some agencies may have specific policies regarding magazine modifications.
What's the difference between this and the pre-installed version?
The Springfield Echelon +5 Pre-Installed Magazine Extension includes a complete OEM magazine with the Shield Arms extension already professionally installed, tested, and ready to use. This standalone extension allows you to upgrade your existing magazines. Choose the pre-installed version if you need additional magazines, or choose this extension to upgrade magazines you already own.
Will this work with aftermarket magazines?
This extension is designed specifically for OEM Springfield Echelon 17-round magazines and is not guaranteed to fit aftermarket magazines. Aftermarket magazines may have dimensional variations that affect compatibility. We recommend using OEM magazines for optimal fit, function, and reliability.
How do I access the spring and follower with the easy-access design?
The easy-access floor plate features a simple hand-operable mechanism that allows you to access the magazine internals without removing the extension body from the magazine tube. This design enables quick spring inspection, cleaning, or follower service in seconds rather than requiring full disassembly. Detailed operation instructions are included with your extension.
Is the extension durable enough for duty use?
Absolutely. The Shield Arms Echelon extension is CNC-machined from billet 6061 aluminum—the same material used in aerospace and defense applications—and features a Type 2 anodized finish for corrosion resistance and durability. This construction provides superior impact resistance compared to polymer base plates while maintaining reasonable weight. The extension is built to withstand the rigors of professional use and is backed by our lifetime warranty.
Can I return the magazine to standard capacity?
Yes. If you wish to return your magazine to factory configuration, simply reinstall your original OEM base plate. The Shield Arms extension installation is completely reversible and causes no permanent modification to your magazine. Keep your original base plate for future use if desired.
