Pumpmaster 760 Clip

I tried printing the original one made by davachat which was a very accurate replica of the original injection molded clip. But it didn't work for me it was much too loose the pellets fell right through the clip and the clip fell right out of the pump master 760.
I redesigned the clip with the advantages of 3D printing in mind.
My design is much tighter fit and has a spring load to keep the pellets in the mag. if you have any advice for a better mechanism please let me know.
