Just bought a new G 36 but have a problem with the magazine hanging up in the well when I insert it. Feels like the release button in the well is catching on the upper lip of the magazine. This caused the plastic laminent on the magazine to bend over and is peeling off. Only way to stop it from hanging up is to partially push the release button in when putting in a mag. Anyone had similar problems. Glock said they'd fix it but it'll cost arounb $50 to ship it to them. Do they reimburse customers shipping fees since it's warranty? The line is always busy when I call.
