I've not seen that...just the IPSC shooter one position over that used a Glock as his "race gun." Quickdraw, double-tap, holster. He was very impressed with himself and his speed. Let all of us know that if he shot as well this season...he'd make Grand Master.
And then while I was practicing with my 1911, I sorta saw the pull, heard the double-tap, saw the movement to holster, heard the shot, the scream, the drop.
I gotta tell ya, that "self-aid, buddy care" they taught us prior to deploying to a combat zone...that stuff WORKS!! He had a nice through-and-through of the upper thigh, exiting near the knee. When paramedics arrived, they complimented my use of cleaning patches to plug the holes. I did lose my constriction band though.
Never saw him again at our range. Pity...he became the exemplar of what NOT to do.
