I think I remember Bill Frady saying last week something like:
“Don’t be cautious of the person who practices and trains with multiple guns and calibers. It’s the guy who works with one gun over and over continuously that you don’t want to get on the wrong side of.”

Paraphrasing here, but you get the reference.

I heard it this way:

Beware the man with one gun.

He probably knows how to use it.

That was taken from the old Maxim:

“Beware the man with one gun, for he surely knows how to use it.”
