Objective: To determine whether there is an association between criminal activity and preference for a particular class of handgun among young adults who purchase handguns legally.
Design: Historical cohort study.
Materials and Methods: Subjects were 5,360 authorized purchasers of handguns in California in 1988 who were 21 to 25 years of age, divided into two groups: all eligible purchasers with a previous criminal history (n = 2,765), and a random sample of purchasers with no such history (n = 2,595). Handguns were classified as small and inexpensive or larger and expensive. Associations were assessed by relative risks adjusted for gender and race or ethnicity.
Measurements and Main Results: Handgun purchasers with a previous criminal history were more likely than those without such a history to purchase a small, inexpensive handgun (relative risk (RR) = 1.28; 95% confidence interval (CI), 1.16-1.42). Among handgun purchasers with no previous criminal history, those who purchased a small, inexpensive handgun were more likely than purchasers of other handguns to be charged with new crimes after handgun purchase (RR = 1.73; 95% CI, 1.34-2.24) and were nearly twice as likely to charged with new crimes involving firearms or violence (RR = 1.93; 95% CI, 1.38-2.69).
Conclusion: In this population, criminal activity both before and after handgun purchase was associated with a preference for small, inexpensive handguns.
