What is your favorite handgun caliber? It can be revolver or autoloader.

Mine is the 357 Magnum.
Because I can shoot a powerful round and also the wonderful 38 Special, police choice and a bad-guy stopper for many years, even when the 45 Colt round was available. You can shoot both with in a 357 Magnum revolver.

Next, 9mm.
Cheap, ubiquitous, autoloader that will get the job done. Still, not up to the 357 Magnum for power and versatility (i.e. 38 Special).

God bless,
