While the design of most single shot handguns shows that they are primarily intended to be used for sporting purposes, this is not necessarily the case of handguns with larger ammunition capacities. Revolvers and semi-automatic handguns, which are designed to be loaded with multiple rounds of ammunition that can be fired and reloaded quickly, differ substantially in design and function from single shot handguns. The likely use of revolvers and semi-automatic handguns in the community varies, and the projectiles they use are, in many cases, interchangeable among models designed to use the same or similar calibers. Consequently, it is not possible to conclude that revolvers and semi-automatic handguns as a class are “primarily intended” for use in sporting purposes. Similarly, most handguns designed to be loaded with two-rounds of ammunition are small-frame, easily concealable, derringer-type firearms. While two-shot derringers may share certain design characteristics with single-shot firearms (for example, a break-open loading function), they are not useful as sporting firearms.[/
