Henning Group's EDC Magazine Extension is designed to give you three more rounds in your Sig Sauer P320. Extends 3 rounds in either 9mm and 40 S&W magazines, compact, standard or long length magazines! Use with factory magazine spring and follower. The factory locking plate is NOT used.

Fits Sig Sauer factory 15 round, 17 round and 21 round magazines !

The EDC extension comes with a side cutout to enhance magazine grab / pullout. This product is CNC machined from 6061-T6 aluminum and anodized in black. The spring loaded detent is made from stainless steel and finished in black nitride for long life. 

These extensions are designed to work with the Sig Sauer P320 X-Series models (XFIVE Legion, AXG Scorpion, RXP XCOMPACT, XFULL, XCOMPACT, XVTAC, RXP XFull-Size). It will also work with the Wilson Grip Module and other after market grip models with a flat bottom. If  you want to use it with standard P320 grip modules where the back strap comes down, it will require modification of the grip module to allow for relief for our steel detent. This is how the extension is held in place so standard P320 grip modules will need a relief cut into the grip.

Does NOT WORK with AXG PRO with Magwell !!!
