See, I think it would slow down your draw, at least in comparison to an OWB belt holster and swing-away cover garment.

It would also make the initial grip a little fumbly. You'd have to practice like crazy with it.

And - it limits you to smaller guns, which are pretty easy to conceal anyway.
On the other hand - for those tradeoffs, you do get much better concealment. And you can tuck in your shirt without the shirt obstructing your access like with a "tuckable" holster.

I don't have the balls to carry OWB with a swing away jacket or coat, I can always imagine it flipping up in a breeze and Whoops. Or I jump on my Bike and forget to zip or button and get pulled over for brandishing a weapon. Plus it gets too hot around here to carry that way except in winter.

The above video shows you cant get your finger on the trigger until you have started to pull the gun, with practice I think it would do fine, plus all of use should automatically index every gun every time we pull it, so you would be using your bird finger to pull the gun out.
