Clip extension
Had to sand it down the top where the extension plastic meets the clip, needs to be made a little short i had to really slam it in the mag well inorder for the mag catch to catch the magazine, but the extension is for a xd i have a xdM so maybe the elite clip is a little wider then the regular cd clips but i made it fit it feeds find the spring works flawlessly i love it!

Great product
This spring and floor plate is a great product for gaining reliable capacity and adds grip length. Can't go wrong!

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...

XD40 magazine extension
Ended up only being a three round extension instead of the advertised 4 additional rounds. Definitely doesn’t look like it was designed to match the XD40 grip but instead is a weird smooth extension that is smaller in diameter than the grip. Fortunately, no issues feeding even with a full mag dump.
