Lucky is a unique version of the standard .357 magnum revolver. In comparison it deals more Damage and has a higher fire-rate and Critical Chance. The barrel, frame and chamber are made of a smooth black metal decorated with ornate gold etchings, and the polished ivory handle is inlaid with the clubs symbol. The word "Lucky" is imprinted on the silver plate on the ejector tube.
Like most unique weapons, weapon modifications cannot be used on Lucky. However, it comes with the long barrel modification already added. Furthermore, it is considered an improved holdout weapon, and can be concealed and taken into weapon-free locations so long as your Sneakskill is 50 or greater.
Lucky can fire a total of about 1120 standard rounds, the equivalent of 187 reloads, from full condition before breaking.
Lucky is found in a locked floor safe (Lockpick 75) inside the Bison Steve Hotel in Primm. Enter the hotel through the main front entrance and proceed through the doorway ahead. Follow the corridor and enter the gift shop on the left. The safe is behind the cash register.
Lucky can be seen on the cover of the Fallout: New Vegas game guide
