There must have been a practicle way, since many gun toters back in the day holstered their loaded CB's and spent the rest of the day, week, month doing their everyday chores. Unlike the movies, westerners didn't spend everyday shooting at stuff. I have seen contemporary photos of cowboys and such wearing a CB revolver with no cap or cartridge box on the belt. Not only was the weapon loaded (presumed) but they obviously didn't intend to need a reload. I wonder how corrosive unfired BP is in a cylinder over time?
