Whatever you choose you will need to master, period.
Yes, heavy kicking revolvers (like heavy kicking rifles) require practice to master and some may never get to an acceptable level (same applies to heavy kicking rifles)...My point is that whatever you choose to defend your life with (or the lives of your families and friends), you had better practice to a level of competence if any of it is to be effective.
I don't think anyone argued this point. And @Walkalong pretty much said as much, while trusting you are one of the individuals who have put the effort in.
