Hardest handgun for you to shoot well?

Kel Tec P40
if you want to know how it feels to shoot one
just grab a small ball peen hammer
and start pounding your hand...

Another vote for NAA Mini Revolver. I've heard stories of people who claim to be able to put all five rounds in a dime at a hundred feet, I'm doing well to hit paper at ten feet with mine. Trying the holster grip helps a little, but not enough for me to be happy with it.

The Pug might be better for me since it has an actual set of sights. But I'm sort of "eh" on dropping $300 just to see (when I could instead put that $300 towards something I'd be a little more enthusiastic about).
