Hey there, I own, to my knowledge, a discontinued KWC Desert Eagle .50AE Gas blowback pistol. I have been missing some parts for this gun for quite some time. (Some more important than others). I am missing a firing pin and a mag catch which i can neither find a replacement for online. Does anyone have any idea where i may be able to find these parts as i would like to get the gun back in action. Thank you in advance.
