you sound like a pretty big guy at 6'2" so am thinking the 38 and the shield might not be all the comfortable for you to shoot because of hand size .. the other 2 are almost too large to pocket carry so an IWB holster I think would be best and the most comfortable for you .. also pocket carry is the slowest when trying to draw your weapon and the hardest to get a proper grip on the weapon to fire it .. all of this taking the time to get yourself killed ..
Try to shoot each of them before deciding on what might be a bad decision for you if you don't .. and see how they might fit in your normal pants pockets .. and how you do drawing it from your pocket .. of course do this with a holster and it unloaded .. practice drawing is done with a safe unloaded weapon !!
