A Springer Precision +3 Magazine Extension specifically designed for the XMACRO 17rd mags from Sig Sauer. These have a discrete extended tip set screw in the back that keeps the magazine secure. The mag extension is profiled to work with magwells and has added traction to the bottom to assist with reloads. The traction gives just enough texture in your palm to keep it from sliding, but is not sharp if you are practicing reloads.

Custom engraved and custom colors are non-returnable.

*We include a 1/16 hex driver that makes installation and removal a breeze.  

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