Extrinsic safety devices, such as trigger locks, have been central in the recent state discussions on how to reduce firearm injuries. The actual prevalence of handgun locking devices in the consumer market, however, is unknown. This study catalogued the extrinsic safety devices available from handgun dealers and discount retail chains in Milwaukee, WI. ⋯ Other types of devices included lock-boxes (n = 5), cable locks (n = 4), hammer locks (n = 1), barrel locks (n = 1), and a rubber slide strap (n = 1). Handgun owners in the Milwaukee metro area have a selection of extrinsic handgun safety devices available from handgun dealers and discount retailers. However, there does not appear to be a consistent availability on type of device.
