I have one of the Smart Carry's - it is comfortable in just about any position once you get used to it. But it still takes two hands to get the gun out, and the actions required to extract the gun are not exactly subtle. Kind of looks like you are pulling your pants out with one hand so that you can reach in and scratch or adjust your johnson with the other. Not something people do in public without arousing suspicion. Forget standing there with your pistol in your hand with the Smart Carry - No way you could carry that off, you would look like the pervert of the decade.
I wore the smart carry, and several other styles of carry for quite awhile and finally settled on pocket carry, which is one the main reasons I love my CZAK - it fits into my pants pocket nicely, yet packs a reasonably hard punch. I can easily stand with the pistol actually gripped in my hand and not be at all noticeable. After all, a lot of people stand with their hand(s) in their pocket(s).
I can get my CZAK out and into operation in a split second and without having to dig around in my crotch to do it. Lord knows that in an emergency situation when you are pumped with adrenaline you just don't need complications, and pocket carry is extremely simple, extremely fast, and extraordinarily subtle.
I do believe that pocket carry is the fastest draw method you can do and have a concealed gun. Because you can actually have the gun in your hand before bringing it out, and no one knows it. I know this for a fact, as I often find myself standing in line (at the bank or the grocery store or wherever - it is kind of a strange feeling being at the bank with a pistol gripped in my hand but I can live with it

) with my hand in my pocket and since my CZAK is in there my hand naturally rests on the grip. You can't do that with any other form of concealed carry that I am aware of.
In an emergency situation, from pocket carry, I would be able to empty a magazine before someone with a Smart Carry could fire their first shot. And no one would see it coming from me, but from the Smart Carry person rooting and digging around his johnson - well they would be looking right at him wondering what in the devil he was doing.
