Springer Precision SIG P320/P250 9/40 EZ 140mm base pads


Springer Precision SIG P320/P250 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 rounds to your magazine. The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They fit the USPSA 140mm magazine gauge. The unique attachment design provides a low profile, sleek design that is very stable and easy to remove. We include a .050 hex driver that makes installation and removal a breeze. 

*You may need to remove a very small amount of material on the magazine rail that slides into the basepad, very easily done with file/dremel*

*Not compatible with flanges that fold into the magazine body 

**Disclaimer: As with all competition geared changes, always make sure you test and check your gear before you take it to a competition setting.  With 140mm/170mm magazine configurations especially, check the magazine in a USPSA 140mm/170mm gauge to make sure it fits.  With mass produced items like magazines, sometimes they can vary slightly from one to the next, often in the magazine lips that connect with the magazine extension/basepad.
