Springer Precision extended basepads for Walther 18rd magazines are CNC machined from brass for added weight. This lengthens the magazine and adds more traction for easier, more reliable magazine changes. They are perfect USPSA and anyone you wants to improve their reloads.  

Does not fit PDP compact 15rd Mags.

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