Caliber aside, there's an issue with the idea of Sniper Pistols: Pistol Inaccuracy.

Pistols, by definition, don't have long barrels, which means less grooving inside the barrel to give spin to the bullet.

One can make the barrel longer, but the longer the barrel, the harder it is to draw out quickly even from a hip holster, and the harder it is to aim it or hide it. And generally, the heavier the gun will get.

And that's the problem: If you really want a Sniper Pistol, the barrel needs to be long, even if not to Sniper Rifle standards, but then you have either a Rifle with no stock, or a very inconvenient pistol.

Now, if you really are a good-enough marksman with pistols, then you don't need a longer barrel or anything (Ex: Jerry Miculek popped a balloon at 910mts of distance with a revolver from standing position), but that only makes you a sniper, instead of making your gun a Sniper Pistol.
