hi guys! this is my brothers gun, he haven't used it in a while since september. i dont know what happen to it but, when you put the magazine into it, fire it, instead of making it a full cycle, it will get stuck in the middle and slowly release the gas in the magazine. in order to stop it, i needed to release the magazine. my initial though of the problem is that the it does not have any lubrication to it. Could anyone tell me how to open an WE XDM or link a video of a person opening it. somehow i been trying to open it to lubricate the gun but i dont have any luck of getting the slide out of the frame.
please anyone help me.
thanks
JK
