Kinoons, Studies Are "Interesting"...
....for what they are and how they are done. I've never worried about gel and how it equates to a body, two different things.
Two types of "stress", there's the induced physical such as the FBI runs in the run a mile then shoot a barricade course. Any physical activity makes it harder to shoot well.
Then there's the kind where the pressure is on, life and death kind of pressure. Many don't do well with that simply because they aren't used to it. Others are used to the pressure of critical circumstance stresses and that type brings in a better focus that simply means they are going to hit exactly what they are aiming at because it's critical that they do.
It's hard to argue what's good enough for different people. When this subject comes up I generally enter in the fact that the smaller a .380 gets the harder it is to shoot and follow up shots with.
This topic being about hollowpoint specialty bullets versus solid points, hollowpoints are going to do more damage. How much penetration do you need for a chest/heart/head shot? If your shot is somewhat off damage is the factor not whether it goes through the person. If you need to enter in the damage involved with lousy shots maybe (you do) need a bigger caliber, may the force be with you cause you're gonna need it.
I suspect there is a difference between my .380 Beretta model 86 reference and the little pocket guns many are referring to when they want to analyze .380's. This is a 50 yard accurate pistol that is easy to shoot fast. At 15 feet anything I shoot will be within an inch of where it was meant to be.
I'll opt for the damage a hollowpoint does versus a solid point, and stick with the bigger gun platform as well, it fits in my inside jacket pockets and 4:00 belt position just fine. It's not really "small" but it's small enough.
Went out shooting the other day with a friend, we had four or five pistols and this .380 was the one we put three boxes of rounds through shooting at cans between 20 and 35 yards. Little pocket .380's do not garner that kind of enthusiasm, we had a .40 MilPro, a S&W 1911 .45, a Diamondback .22, and a Python .357 as well.
One other thing, we shot three boxes of ball solid points, and some CorBons and Talon hollowpoints. There is a considerable amount of kick and snap that isn't there with the standard ammo. This will undoubtedly contribute to much more steam in terms of velocity and power.
