What is your favorite caliber hand gun?

.40

I have a .45 and .40 for lite days. :-)

I have a .22, .38, 40, & .45. Would carry the .45 if I could get the same conceal-ability and magazine capacity as the .40. My next one will be a 5.56 though.

We have constitutional carry, so I can wear mine in a holster. I also have a old .22 that is just for screwing around.

I think everything should be constitutional carry, but for me, concealed is the only way to go. If I am anywhere near a bad guy, I don't want him to know I could compromise his plans until it is too late for him to respond to him being aware of my weapon.
