140mm Magazine Extension for Sig Sauer P320 9mm 21 Rd Magazine
Springer Precision 140mm extended capacity basepads for Sig Sauer P320/P250 9/40 21 round magazines are CNC machined from aluminum and hard anodized for a long service life. An additional round can be added if you choose the Grams follower options. The unique locking mechanism allows a very solid attachment with a 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.
This is a new style from our previous version that is more durable. Black, Red, Blue Photots will be updated soon. Black, Brass and Raw Aluminum extensions are the new design. Now compatable with 15rd, 17rd, and 21rd mags. Also compatable with our X5 magwell with 17rd mags.
*We include a 1/16 hex driver that makes installation and removal a breeze.
Aluminum .44 oz
Brass 1.43 oz
Custom engraved and custom colors are non-returnable.
*Not compatible with flanges that fold into the magazine body (P250, P320 Subcompact 12rd)."
**Disclaimer: As with all competition gear 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.
