Greetings! Are you looking for a single shot, bolt action, revolver, or semi-auto? There are currently produced pistols in all these categories.
Though AMT used to make one, in a semi auto [also available in 17hmr] there is currently the Accelerator, which may be read about here:
Excel Arms
S&W, Taurus, and Ruger make or have made revolvers in this chambering, in single shots there is the TC Contender, and if you go custom you can get it in the Encore, and also Anchutz and Savage make bolt action pistols in this chambering.
What sort of shooting are you wanting to do?
Also there is the well loved and highly recommended concept of having at least two or more different types of handgun in a given cartridge
