The Cold Steel . 357 Magnum Blowgun offers hours of fun in a super lightweight, budget friendly package! The . 357 Magnum Blowgun is a joy to use, and equally at home hunting small game or target shooting with family and friends. Made from durable high grade aluminum with a TPR rubber mouthpiece, quiver and hand guard – they are much more durable and accurate than many of the novelty “toy” blowguns on the market today, while remaining small, lightweight and inexpensive enough for beginners or younger users.
