Abstract: An improved security holster comprising a solenoid having a plunger member positionable in a locked gun position wherein the plunger member extends through the trigger guard of the gun when the gun is disposed in a pocket defined by a holster body and positionable in an unlocked gun position wherein the plunger member is retracted from the trigger guard of the gun. The solenoid is connected to a power source and a magnetic reed switch is interposed between the solenoid and the power source to allow electrical continuity to be established between the power source and the solenoid by placing a magnet, located on an individual's hand, near the switch. In an energized condition, the solenoid positions the plunger member in the unlocked position and in a non-energized condition the plunger member is biased in the locked gun position.
