Springer Precision 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 capacity to your magazine with the factory follower. Up to 23 rounds of 9mm and 20 rounds of .40 when paired with Springer's extra capacity follower kit. 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 mag wells 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.
