Sig Sauer P320 - 140mm EZ Basepads by Springer Precision

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. More rounds can be added if you choose the Grams follower options. 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. Up to 23 9mm and 20 40. cal rounds with the extra capacity follower kit. 

  • *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
  • Weighs 1.40 oz
  • Holds 19 Rounds Reloadable, 20 Rounds Non-Reloadable with included spring
  • Holds 22 Rounds Reloadable, 23 Non-Reloadable with Grams Spring and Follower Kit

**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.

Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified. Please call us with any questions.

Springer Precision has indicated that some fitment maybe required on the magazine to make the basepad fit. This may mean simply sanding on the bottom of the magazine.
