Pistols just the same as any other airsoft gun that does not have a clear receiver - or slide in the case of pistols - is illegal to import. You can still own the gun you juts can't bring it into the country on your own.
Best advice if you're looking for any airsoft gun is to fill out your profile so we know where you're located, and get age verified. This will open up a few more ares of the site to you and give you access to the retailers.
