You might want to look at a Thompson Contender Pistol or if you want a Bolt Action you should be able to buy (secondhand) a Remington XP100 Pistol.

or even a Savage Striker Pistol (pretty much the same thing as the XP100)

Reminton and Savage dont make either of them any more but you should be able to pick one up secondhand.
