The Don Maccy always loved a good weapon. One day, he invented a special device called the Maccy Pistol. It was one of the first ring-pistols.
By pressing the sides of the golden nugget on the ring, it would shoot out the piece of diamond, following a small bullet. The size of the bullet was extremely small, allowing it to penetrate more areas of the body and going deeper inside.
The only known way to purchase this kind of weapon is to contact one of the Don Maccy's Smacky Maccys and receive the "Helping the Maccy" quest.
