I am having a problem with one of my high cap mags for my Glock 19. It loads fine but when it is feeding the ammo into the gun the ammo gets stuck down in the tube. I have a bunch of the same mags and this is the only one that I have a problem with. I have tried to rebuild the mag and it is still doing it. Any suggestions would be appreciated. Or does anyone know if Glock would fix it if I sent it to them? Again any help would be appreciated. Thanks Wanna kill these ads? We can help!
