I appendix carry. It's the only method that I can conceal completely no matter what I wear. When I first started carrying, I tried the usual 4 o'clock, but the damn grip would be so obvious when sitting or bending over to pick something up. And that's with a small single-stack 9mm. I even tried the huge hybrid holsters with 2 belt clips and couldn't stand the ordeal it takes to put on and take off the holster.
I'm a 32" waist and sitting down while carrying appendix isn't bad at all. It's gotta be single clip Kydex IWB for me from here on out. I can take my still holstered gun off in a matter of seconds to put in my vehicle's lock box when needed and vice versa.
Thanks for posting the video. I've seen it before but I couldn't find it again when I wanted to show a friend of mine.
We've done hot drills before with draw and shoot with a timer. I can do sub 2 seconds easily from appendix concealed. But that dude is insanely fast.
And, I'm not worried about blowing my junk off. I've practiced a lot ( i mean A LOT) when home doing dry fire drills just to build up my muscle memory. A good Kydex holster and good trigger discipline and practice practice practice. No worries.
