Conventional wisdom abounds in shooter's forums. Everyday, I hear that trite phrase parroted.
"A well-placed .32 ACP is better than 4 - .45 ACP's that are not center-mass, yadda, yadda".
How many really think an adversary(s) is going to present a frontal, stationary, unobstructed target? We're not talking paper punching....caliber matters.
