LOCKS FOR FIREARMS

摘要

A lock, for a firearm with a revolving bullet-receiving cylinder, is inserted into one of the chambers of the cylinder when the cylinder is in an open position. The lock comprises a body (2), insertable through a chamber and then expandable at foot portion (6) by turning a key (7) in order to prevent withdrawal of the body. While the body remains within the cylinder, the cylinder cannot be closed and the firearm cannot be discharged.
