Hardcast the first and only bowling pin shoot I was at was exactly like that except for mag capacity. You were only allowed 6 rounds in each if 2 magazines. It was the only one because I was invited to it by my friend in FL. It ended up I won the whole "shootin match" with my Taurus PT1911 ! On the final round my last pin hit the ground just as my opponent's was rolling off the table. My time was 2.6 seconds! That was the most fun I ever had with my clothes on.
