It's nice to see some common sense about self defense like this once in a while.
Too many new CC licensed newbies buy into the "huge bullet" or "lots of bullets... plus more bullets" mindset for self defense.
All of that is nonsense, and a J-frame with 5 rounds of regular old hollow point .38's will get you out of serious trouble in any real world situation.
Note that I said "real world" situation, because these newbies so often fantasize about getting on a bus with 15 gang members and similar such nonsense.
I've mentioned elsewhere that if you read "The Gift of Fear" by Gavin De Becker, you will virtually NEVER allow yourself to get in a situation where you need to shoot, and if you do, a .38 snubby will get you out of it.
In all the years that I've been carrying (yes, many years before it became "legal" to carry... my "license" was the Constitution), through situational awareness, there have been only two times I have been in situations where I thought I might have to draw, and one of them involved just one person, and the other involved two people.
In both cases, just my attitude and body language that indicated that I was both willing and able to seriously hurt them stopped any further discourse and led to their vigorous exit from my view.
So yes, it's nice to see a SD "professional" talk common sense about practical considerations of the kind of weapon that is more than sufficient for self defense in the real world.
The term "stopping power" should be eliminated from the discussion anyway. Shot placement is everything, and if you really want to make a person "stop" immediately and fall to the ground, just shoot them in the groin/lower abdomen with ANY caliber. Now that's stopping power, even with a .38 J-frame.
Think about that for a moment, and do you recall ANY incident of ever getting kicked in the groin (yourself or anyone else) and being at all able to stand up straight, let alone keep moving? Think about it.
