I have a new XDM Elite that will not fire. Everything works like it should but firing pin does not strike the primer hard enough to cause it fire . There is a slight indentation on the primer but not hard enough to make it go off, tried all brands of ammo all have the same slight mark. does anyone know what is wrong with this gun, I purchased gun new in the box and there are no marks or dents of any kind on it, Has anyone had a problem like this or have information about this problem,
