Can’t imagine one is made. Not much of a market. EZ is he size of a 3913. Bigger than a standard Shield and that’s no ankle gun either. You’d have to wear blousy pants at the ankle to even clear the grip.
Galco makes an fairly universal ankle holster that I carried a Shield 9 in a couple of times. The holster was fine but I found the gun to be to big for my liking and went back to ankle carrying a J frame as a BUG.
