The grip folds up to allow for easy concealment and carry and folds out into a locked grip for more convenient use and control. It is versatile for many applications and is the standard by which other Mini Revolvers are judged. As with every NAA Mini Revolver, the hammer need not rest on an empty chamber. Using the original half-way notch cylinder, the hammer may rest safely and securely without chance of accidental discharge. Order today!
