Springer Precision XDM 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 3-4 rounds to your magazine. More rounds can be added if you choose the Grams follower options but the slide will not lock open when the magazine is empty. 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 our mag wells and fit the USPSA 140mm magazine gauge. * We include a .050 hex driver that makes installation and removal a breeze. There will be a gap between the base pad and frame if used with a compact model.
1.09 OZ, Black in Color
- 22 rounds with stock follower (9mm)
- 17 rounds when used on the 13 round compact magazines (9mm)
**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.
