Between 1977 and 1983, eighty-eight California children 0 to 14 years of age were unintentionally shot and killed either by other children or by themselves. The majority of cases occurred while children were playing with guns they had found. Easy accessibility to guns, the resemblance of guns to toys, and gun malfunctions were all contributing factors. Handguns, particularly those of .22 caliber, were frequently involved.
