Re: For Conceald Carry; A .22 Mag, .32 ACP or a .38 Special?
MY opinion only. I see no point to a .22 or .32 for self defense unless your VERY good and train a lot.
I have trained many people in defensive shooting over the years, if your NOT going to invest the time, the larger caliber is better, IMHO.
That's MY opinion, take it for what it's worth. As far as I'm concerned, .22 is for huntin' squirrels and such, and the .32 is SO close to a .380 acp in physical size, why bother?
Incapacitation is the issue, and I don't believe that the .22 or .32 is all that good without precise placement.
As a last ditch backup maybe, but not for your primary piece.
As an aside, I had a customer shoot himself in the shoulder on the range with a .22 mag from a NAA mini-revolver, he was calm and walked out to the ambulance with no vislble ill effect. Near total penetration, chipped the collar bone too. And yes, it was an H.P. bullet. And no, he admitted he's no tough guy. No .22's for me for self defense.
You are what you do, when it counts.
