The 22 Mag cylinder can be used with all popular .22 Magnum ammunition, including .22 Magnum shot shells. This model comes with a special 22LR conversion cylinder made longer to easily fit in the.22 Magnum mini-revolver. It is lightweight and has a 5-shot capacity. Using the half-way notch cylinder, the hammer may rest safely and securely away from live or empty chambers without chance of accidental discharge. The steel frame is fitted with a locking black holster grip with a pocket clip and fixed blade front sight. The holster grip unfolds and locks to become the handle of the gun. Press the release button and the mini-revolver folds back into the grip. For added safety, when the holster grip is folded, the trigger of the gun is completely closed.
