    Few studies1 have examined variation in firearm policy opinions among firearm owners, even though these policies, which may target specific firearms or behaviors, may not affect all owners equally. In addition, the confluence of individuals’ firearm-related practices and motivations may reflect differences among owners that are unmeasured (eg, concern for safety) or unobservable (eg, culture) and that are associated with policy opinions.

    With use of a state-representative survey of California adults, a previous study2 identified 5 latent classes of firearm ownership based on numbers and types of firearms owned, the primary reason for ownership, firearm storage, loaded handgun carrying behavior and motivations, and high-capacity ammunition magazine ownership. In this study, we assessed whether those patterns were associated with variation in opinions on 3 selected firearm policies.
