Pistols that shoot up to 1000 fps?

Are there any pistols (BB, Airsoft, co2) that shoot at or near 1000 fps. Not rifles, but pistols of any kind. My friend claims he has one. I still haven't seen it, but he said that it looks realistic, shoots at 1000 fps, and it shoots these "mini bullets" or some sort of metal projectile shaped like a bullet. Now I'm not sure how true that is, but he has this whole arsenal of Airsoft guns, so I'm positive that he at least halfway told the truth. He also said that alot of people call the guns "cat killers" because they are capable of killing cats (and other things the size of cats). Now I have an actual BB gun that only shoots around 760 fps. So If anyone knows about this gun or a gun similar to it, please post a link or tell me what kind it is and where I can get it. Thanks!!
