The Springer Precision extended basepads for Rock Island Armory 9mm (TCM 9R) are CNC machined from aluminum and hard anodized. This lengthens the magazine .25" to make for easier, more reliable magazine changes. They are perfect for IDPA, ESP and USPSA.

Custom engraved and custom colors are non-returnable.

If your factory basepads do not have a floor plate and attach by clipping on the rear, then you will need to select the appropriate option from us to include a machined floor plate, otherwise your basepad will not securely attach.  This is the style found on the ACT mags, 10mm mags, etc.

Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified. Please call us with any questions.

May or may not work with RIA 9mm Tac Ultra FS HC due to variations in the magwell that we cannot confirm visually or by model number.

*Fits Para 15rd 10mm mags, fits P16 .40/10mm mags.*
