XD9

I have been trying out a few other companies for mag extensions. AGP has been my favorite so far. I will be ordering more for all my XD9 16rd mags, which will all be 20rd mags now! Awesome fit and finish as well.

XD +4 magazine extension.

The magazine extension and spring work great. You will need a punch to install.. and perhaps a flat screw driver.. Have used them in USPSA matches and they hold up very well..A must have if you compete with an XD...
