in all seriousness, I would be inclined to not suggest a +p round in the snub for anyone who isn't willing to master them. There is a large difference between handling for every change of ammunition, be it a 110+p or even a 158 sub sonic velocity.
IMO, it may be a safer, better alternative for a snub to be loaded with a good combat 158 grain at standard pressure. I have not personally handled a snub, but a standard smith K frame 4 " barrel gives widely varying results in all aspects of shooting. It makes a difference.
Also important, everyone should keep in mind that 12" is a GUIDELINE and not carved in stone, and not achieving the guideline will not result in a time out or a spanking. People have been killed even after putting 12 inches through their opponents. Men fought through combat with 30 caliber battle rifles with lethal wounds. Nothing guarantees survival. Likewise, nothing on this planet guarantees that you will lose a gunfight, but a person's chance of surviving one get very poor if a poorly chosen weapon is used.
Don't use an underpowered weapon and fail to disable the opponent. Don't use an uncontrollable weapon and miss or fail to disable. Don't buy one that you leave home, and thus present no threat to the opponent.
MAKE WHATEVER COMPROMISES YOU MUST MAKE TO ENSURE THAT YOU HAVE A WEAPON THAT YOU CAN COMFORTABLY TRANSPORT, USE WELL, AND WILL USE AT ALL TIMES, THAT WILL STILL HAVE THE POWER TO CAUSE SERIOUS INJURY.
It's all a matter of learning what handguns are appropriate and then choosing one.
And to the point, I suggest a standard pressure .38 in 158 with good hollow points, in a snub, if that is what you choose. Trust me, the 158 grain .38 special in quality ammo is every bit the equal of the 115 grain 9mm for practical purposes. either one will cause serious wounds.
