Practical measurements of defensive ammo effectiveness

A police officer's recommendation for self-defense against an attacker hopped-up on the latest generation of synthetic marijuana generated some discussion.  I was struck by how many of the comments ignored the point of the police officer's advice, which was:

... typical deep-concealment (i.e. small, lightweight) pocket revolvers and pistols are simply not adequate to deal with people under the influence of this stuff.  His personal opinion was that .32 ACP, .380 ACP, .38 Special, and even 9mm. Luger or .357 Magnum rounds, if fired from smaller weapons whose barrels aren't sufficiently long to give high velocity and promote bullet expansion, are not going to get the job done against a hopped-up addict who won't even realize he's been shot.

His advice was specifically limited to small, deep-concealment firearms, the kind of thing many of us drop into our pockets rather than worry about putting on a holster and carrying a full-size firearm.  It was not intended to discuss the latter at all.  However, a number of commenters ignored that caveat, and responded as if he were making a general statement about all defensive handguns and ammunition.  That was not the case....https://bayourenaissanceman.blogspot.com/2018/11/practical-measurements-of-defensive.html
