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!

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