We've had several threads recently that have shown, to my mind, inscrutable consistencies. One side always comes in with 'Handgun stopping power is a myth. and all handgun calibers are essentially within 20% effectiveness of each other. One poster asserted that the .357 Mag. is no more than 20% more effective than the .32 acp. OK, let's just think about all of this logically. If really, all calibers were only about 20% more effective than a .32 acp, we would all choose that caliber. possibly in bigger guns/different bullets but case closed. Cheaper ammo, lower recoil, more rounds on target, we're done. In the real world, where we could all get shot and killed, there exists a spectrum of handgun power. For now we'll take the .32 acp at the low end and move on up through the various popular calibers to .50 ae. (we're only considering semi-auto calibers here although a similar argument can be made for revolvers). Now the first question you need to ask yourself: Is .32 acp as effective as 9mm in humans? Let's move up a little in caliber: is .380 acp as effective as .40 S&W in humans ? ok, lets reach a little higher: is .32 acp as effective a .45 acp in humans ? How about .380 acp vs. full house .357 Sig or .460 Rowland ? The 'all handguns are the same' crap maffia will lead you to believe that all of these calibers are equivalent for the simple reason they are fired from a handgun. I call BS on this logic. Sure handguns may be less powerful than rifles but they are not all the same.
