There is a school of thought that says the JHP rounds are unpredictable. Some may perform exactly as they are designed to. Some may clog with clothing and not expand at all. Some may fragment early and not penetrate as far as they need to. Some may start to expand in clothing and not penetrate enough. All of these rounds may come out of the same box.
Me? I like exit wounds. The fight stopping condition known as hypovolemic shock is likely to happen sooner if your attacker has an entry hole and a drain hole. With a drain hole blood accumulating in a cavity is much less likely to slow or stop bleeding from a vessel or organ injury.
Right about now a bunch of people are pulling out their keyboard trays and getting ready to rip me a new one. Let me save you the trouble. I know the over-penetration fallacy. Every bullet you send down range has a lawyer attached to it, innocent women and children, can travel for miles, and on and on and on. Pay attention.Statistically at least one of your rounds is going to miss the attacker completely.
There is a post here somewhere about a training session in which pairs of trained people faced off against each other with training rounds. They knew what was going to happen, they knew where it was going to happen, within a short time span they knew when it was going to happen, and they knew it was going to hurt. They missed 15% of the time under the best of three scenarios and it got worse from there.
The round that misses will carry a lot more energy than the one that just had much of it's energy depleted traveling through your attacker. The only 100% foolproof way to avoid shooting the bystander is to leave your gun at home. If you carry a sidearm for self defense there is a high degree of risk attached to it. If you don't acknowledge that risk and train to minimize it you risk endangering the bystander. Changing your ammo to make up for careless shooting technique doesn't get it.
