Depends on which pistol you had in mind. For semi automatic pistols, 10 rounds is usually the norm. Revolvers may hold six or seven. Of course, there are those oddities, such as pistols manufactured from 10/22 receivers (these have to be assembled from newly manufactured aftermarket receivers to be classed as pistols - if they're manufactured from receivers which were already used to manufacture a rifle with, it's no longer considered a pistol, but a short barreled rifle), and those can accept any capacity magazine designed for the 10/22.
