This was on a Miami Vice episode a number of years ago. I'm fairly certain it is an appendix carry cross drawn. His Name is Jim Zubiena. He was accomplished IPSC shooter a number of years ago. Just to make things clear IPSC is shooting paper and steel. No one shoots back!! But I think it demonstrates what is possible after years of dry and live fire training. I shoot IDPA and IPSC and have only been at it a few years.
