I knew a guy who had a larger-size pocket pistol in .25 ACP.
I'd never fired one, then, so when I visited his farm we took the pistol and an empty cardboard oil can out in a field near the house.

We set it up against a dirt bank and I fired a magazine at it.
The can stood there through the whole thing, almost unmoved.
I was less than impressed with the round, the gun, and my lousy aim.

When we walked up to look at the can it was full of holes and most were
right where I'd been aiming. The can was so light that it didn't move
as the bullets passed through. I did see it kind of shiver once. One of
my shots went low and hit the top of the metal bottom.

I picked up a Bauer later and carried it a bit. It fit inside the top of
my old cowboy boots best. Haven't fired it in a while. If the snow
ever melts maybe I'll take it out again.
