Springer Precision

M&P 9/40 170mm Magazine Extension

$54.50

Springer Precision M&P 9/40 170mm extended capacity base pads are CNC machined from aluminum and hard anodized for a long service life. This lengthens the magazine and allows up to 28 rounds to your magazine with the factory follower.  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 170mm magazine gauge. The unique attachment design provides a low profile, sleek design that is very stable and easy to remove. * We include magazine spring and a .050 hex wrench that makes installation and removal a breeze.  2.66oz

*Not compatible with the low-capacity magazines with the plastic-block bottoms*

**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.
