I have been carrying since 1981 and like you, I have carried in every position with many types of holsters finding many of both that I like. However, after training from all of these carry locations, I have come to the absolute realization that pocket carry allows me to put bullets on target before ANYONE can that is carrying in other places whether IWB or OC. The reason for this is that when I am going about my business I almost always have my right hand in my pocket and on my gun when I am in any area that places me at a higher risk than normal such as parking lots, around structures and in unfamiliar environs.
Also, I believe that if my attacker can have his hand on his weapon, I can too. So, I pocket carry more than 90% of the time now and wouldn't have it any other way.
