.22 for training
In my opinion, utilizing anything other than a duty load for cqb is nuts!
The .22 is a great round for training those not accustomed to the fundamentals of firearms, but not for combat.
I am a certified weaponscraft instructor for law enforcement, and as such, I would refuse to participate in any such nonsense.
In my 50 plus years, this tops the level of stupidity.
