I'm going to bog this jam.
That was from Knob Creek a few years ago. The psitol is the elusive Glock 18. The shooter-can't remember who it is-shot 199 rounds a s fast as the gun would fire. He shot the C-100 and 3 33 rounders if I recall correctly.
The C-100 is actually a modified MP-5 mag (can be made for you: $150 plus the C-100 for a MP5).
Still, I WANT ONE!!!!!!!
