The greatest advantage a revolver has, other than dependability, is marksmanship - most revolver shooters are quite good with their firearms. Watching folks at a public shooting range as a part-time RO, I saw most folks adhering to the 'spray & pray' bottom-feeder creedo, where revolver shooters generally shot bullseye targets - and far fewer rounds. Still, it boils down to what you feel comfortable with, can conceal well, retrieve efficiently, and use effectively. If you don't already own such a firearm - you need to get one quickly - and practice.
You’d be surprised. I’ve known people that would kill for a pair of old sneakers. Not bragging or anything, just the truth. Sometimes people kill or hurt others just because, they don’t even need and excuse.You have an advantage if you use common sense... no one in their right mind would engage in a life or death exchange for pocket change.
Again, not trying to be a wise a** or anything, but you CANT pick your battles. Sometimes you can defuse certain encounters, and defuse situations that would otherwise end up in killing, but other times you can’t, sometimes you don’t even know what hit you.You can pick your battles - avoid many confrontations by using simple analysis - again, common sense. 5/6/7/8 rounds will suffice in nearly all situations... especially if you choose your battles and don't knowingly put yourself in badly outnumbered situations.
