you are wrong... that IS a Glock-related ND...
you see, even WITH a loaded mag in it, you do not need to pull the triggeer in ANY of my Smith & Wesson, Beretta, Ruger, or Dan Wesson, semi-auto pistols...
you can't take them apart with the mag in, so THAT part would be the same... BUT, you don't have to pull the trigger and THEREFORE, your Nd IS Glock-related...
