I would utilize the shell latches too, and let the rounds pop out of the mag tube. Come to think of it, racking 5 rounds through a 20 guage Model 1100 LW earned me one of my most severe a** kickings ever, courtesy of my dad. Never did it again though, and have never had a ND.
A** kickings aside, it is, per Robocop, bad form and unsafe.
