Green light & Red dot, very cool Winmag. That sounds like a very cool set-up. Bet your nephew had a great time with that. Haven't seen one on the range so far.
Too bad you had to share the range with an idjit. Sounds like he was definitely overgunned with that Desert Eagle.
I have large hands, and could not even hold a Desert Eagle securely, so it has never entered my mind to try and fire one.
They had a S&W "Kodiak bear kit", consisting of a S&W .50 Mag five-shot hugh stainless steel revolver with orange grips, in an orange Pelican case, along with other "bear" necessities. You'd almost need bear-sized paws to handle the revolver.
