Yeah I think it was Tripple K or Meggar that made 15 and 30 round mags for the 1911. With the 30 you could just use it as a mono pod to shoot from
I have no clue on how they function as I didnt see the benifit to 3 feet sticking out the bottom of my 1911. Now if it were for a marlin camp 45 that would be neat.
BTW if you decide to go with the 10 rounders go Wilson for the extra $3 over the McCormick mags. I am not happy at all with the 10 round MCC mags I have. The Wilson's work great!!
