i have a glock 20 10mm. when my magazine is loaded and inserted in the gun, the ammo rattles inside. i've tried to tap the magazine from every angle and re-insert. but i still have that rattle. i've even downloaded one, two rounds and still the rattle. i know its probably no big deal, but drives me nuts. makes the gun sound cheap. any idea's/suggestions, or is that the way it is..????
