Frequently Asked Questions

Will this extension work with aftermarket Echelon magazines or only OEM?

The Shield Arms Echelon +5 Magazine Extension is specifically designed and tested for use with OEM Springfield Echelon magazines and OEM-compatible springs. Compatibility with third-party aftermarket magazines is not guaranteed, so Shield Arms recommends pairing it with a factory Springfield Echelon magazine for reliable function.

Do I need any special tools to install this magazine extension?

No special tools are required. Shield Arms includes the necessary screws and hex keys in the box, so you have everything needed for installation right out of the package. The easy-access floor plate design also makes it simple to disassemble and clean the magazine without fully removing the extension from the body.

Is this magazine extension legal to use in California?

California restricts the use and possession of magazines that hold more than 10 rounds. Whether this extension is legal for your specific use depends on the base capacity of your Echelon magazine plus the +5 rounds added. Customers in California should verify the total resulting capacity complies with state law before purchasing or using this product. Goodland Guns recommends consulting local regulations or a legal professional if you have questions.
