I would like to keep my 500 ready with a loaded mag tube but no round in the chamber. After loading the magazine tube, I have to press the action lock lever in order to jack a round into the chamber. This would not be easy or fun to have to do in the heat of a dangerous confrontation. Am I missing a step here? Or are choices limited to keeping the gun with a round chambered (safety activated) or having to push that darn lever at the moment I want to chamber a round? All help most appreciated.
