Where is there a definitive place to get credible data on SELF DEFENSE statistics, especially proximity information. That is how close was the encounter between the bad guy and the armed civilian.

It would seem that if the vast majority of the SD situations occurred within about 3 feet and/or grappling with a single a single bad guy, then the revolver may be the best choice based on the odds. However if the majority of SD is outside of 6 feet and not in physical contact and/or more than one bad guy, the semi-auto mighr be the best choice.

One SD training class I took the Sherrif chief of police stated: “Remember, most predators travel and hunt in packs, and criminals are predators”

His point was twofold: first predators look for the weakest lamb in the herd. Don't be the weakest, pay attention, be alert, walk with intention, be on guard etc. secondly, if a bad guy makes himself known, expect him to NOT be alone. Engage the threat if necessary but look around and do not fixate ONLY on the perpetrator in fromt of you and Get blindsided, as his buddy is pissed off at you for shooting his friend, and attacks you from out Behind or to the side of you.

He also always reiterated that the best gunfight is the one you AVOID! Do not put yourself into bad places or situations/circumstances. and if you recognize you inadvertently stumbled into such a case. Get the hell out of there asap!
