As appendix carry has become more widespread, an increasing number of videos, with folks shooting appendix, are finding their way to the net. Many of these feature "name" trainers and shooters.
Rough guess, but one in ten or less demonstrate what I consider acceptable technique for returning the gun to the holster. Leaving aside Mr_White's videos, and some PF folks, I challenge you to find a video of appendix shooting where the shooter treats holstering as something besides an afterthought.
