What it does: 
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.

    extended base plate

    Posted by Hai Nguyen on Jul 16th 2019

    I was looking for a base plate for my Sig P250 and came across this. I received it in the mail a few days ago. I bought the red one and I gotta say, it is nice looking. Well made and fit perfect. Install was simple. I will most likely order another for my mag.
