I agree, I have never had a pistol become contaminated from powder residue after a shooting session, and my sessions are usually past 500 rounds, at most ill run a bore snake a drip some oil on the rails, but don't clean it. I do see the desire to not have sunburned flakes of powder flying everywhere, but I have never had that issue in a pistol and if i did, I would assume I am probably loading too light. Some powders seem to be smokier than others, especially when running cast boolits, I can't say I've noticed anything else.
