What it does: 
Springer Precision M&P 9/40 140mm extended capacity base pads are CNC machined from aluminum and hard anodized for a long service life. This lengthens the magazine and adds 6 rounds to your magazine with the factory follower. The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They are specifically designed to work with magwells and fit the USPSA 140mm magazine gauge. The unique attachment design provides a low profile, sleek design that is very stable and easy to remove.
