John Taffin created it. "Basically a Perfect Packin' Pistol is a handgun — either sixgun or semi-auto — with an easy handling barrel length between 4″ to 51/2″ chambered in a cartridge capable of handling anything you may run into. It's packable, portable and potent. It may be chambered in anything from .22 LR up to .500 Wyoming Express." In terms of "packing pistol" my understanding is that John was referring to a woods gun, not a CCW for packin on the street.

Mine varies, but is typically a Volkmann tuned Kimber Custom II in 10mm and more recently a Dan Wesson Bobtail Valor Commander in 10mm. Occasionally it's a G23 or SW 44 mag Mountain Gun. Been really digging the DW lately; I give up some velocity but it's packable, extremely accurate, great sights, and will cover 95% of my needs in the woods.
