* Our price includes the extra power spring

Springer Precision 140mm basepads for Glock 17/34/22/35 with extra power spring. Our extended capacity basepads 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. 

1.40oz

*We include a 1/16 hex driver that makes installation and removal a breeze. 

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

*Designed to work specifically with the Glock 22/35. Not designed to work with other models including the Glock 23 and Glock 27.

**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.
