Don't let the tiny size fool you, it is very small but VERY effective! The Wasp 22 Magnum mini-revolver is a great concealed carry pocket gun. The 22 Magnum cylinder can be used with all popular .22 Magnum ammunition, including .22 Magnum shot shells (called Snake Shot by some manufacturers). This model comes with a special 22LR conversion cylinder made longer to easily fit in the.22 Magnum mini-revolver. The Wasp has black pebble-textured rubber grip, a 1-5/8" barrel with a vent bar, and a bead front sight. It weighs 6.5 oz 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.
