I have lower back pain from an injury long ago and any weight on my pelvis aggravates this pain. So, I EDC a 642 with +P loads in a Galco Classic Lite shoulder system. It works great here in S.Fla where big comfortable shirts are the norm. I just leave one button unbuttoned where I can get my hand inside the shirt real quick and the 642 is of a snag free design. The only one who notices the one unbuttoned button is my wife. The holster optional attachments fasten to the pants belt on both sides of the body and the whole shoulder holster system act as suspenders. It's the best of all worlds.
