I agree with Cheapshooter, with one tweak.
LCP in .22mag.
The reason I would like to see the LR version isn't for carry, but rather more economical practice with the same gun as my BUG/deep concealment Elsie Pea

for now I use a very similar feeling Taurus PT22 Poly.
In addition to great practice, it's loads of fun to shoot. I think a rimfire LCP would be as well.
