Patent attributes
Representative implementations of devices and techniques provide locking systems and/or retention mechanisms for an implement holster (such as a handgun holster, for example). Additionally, an implement holster having one or more locking systems and/or retention mechanisms is also described. Locking systems and retention mechanisms may be used individually with a holster or combined for multi-level security of the implement. The one or more locking systems can provide obstruction to the removal of the implement from the holster until intentionally unlocked by the user. Locking systems include hood locks, ejection port locks, and sight covers. Adjustable retention mechanisms can provide a desired retention of the implement while holstered, retaining the implement until a sufficient force is applied to remove the implement.
