Good Lord, it takes five minutes to wipe it off and swab all ten chambers
^^^^^^^THIS^^^^^^^^^
It's not that much of a problem.
The cylinders is the first thing that get cleaned on my revolvers. I shoot revolvers in competition, clean cylinders allow smoother loading (with speedloaders) and smoother ejecting of cases.
It really slows you down if after you dump your rounds into the chambers and have to thumb push some all the way in so you can close the cylinder.
I may not clean anything else, but I'll clean the cylinders after every shooting session, often I clean them between stages.
It really doesn't take that long, I'm sure as heck not going to throw my gun in the tumbler.
