Fir Fer said:True story. I was in a bar in Ocean View, VA. in the early 80's, I lived on 11th Bay at the time, I was stationed at NOB. A fight broke out, I was not part of it. A guy down the bar, say four stools down, about 8 feet away or there abouts, pulls a .25, not sure who he was trying to shoot, but he hit me. The round bunched a hole in my leather vest and lodged in my just opened pack of smokes. So there is no way I would ever carry a .25.
Interesting ancedote but we're comparing .25acp to the .32acp not a 10mm or even a 9mm for that matter.
I tend to doubt that a .32 would have gotten through-and-through penetration in the same situation.
There's a good reason most people who are knowledgeable about guns and ballistics don't carry these wimpy little calibers and lack of penetration is key factor.
With all the wee little .380s and micro 9's available there's really no excuse for trusting your life to a caliber like the .25acp or a .32 either.
