If concealability is a concern, get a flat auto and carry it inside the waistband. Unless you plan to shoot through your pocket at an assailant, I'd skip the pocket carry idea.
I'll tell you what, you get your shooting timer and post your draw times from the holster for your belt carry gun, and I'll post my time with my PM9/pocket holster gun. We'll see who's fastest, except I get to start with hand in my pocket on the gun, cause that's what I do all the time when people whom I percieve to be a possible threat walk up to me. You go for a firing grip routinely on your waist every time some panhandler walks up to you, sooner or later you'll be explaining your actions to the local gendarme.
I stand and talk to folks all the time with about a half-firing grip on my Khar
