幸运是特殊版的.357左轮手枪。与普通版本比起来，它的单发威力更高，开火速度更快，且有着更高的暴击率and uses a low amount of Action Points。它的枪管、框架、和枪膛都是用精密光滑的黑色金属打制，外面包裹着华丽的金色符文；象牙手柄打磨的非常光滑，并且镶嵌了扑克牌里的梅花♣作为装饰。枪管下方的退弹杆上印着银色的Lucky字样。.
Like most unique weapons, weapon modifications cannot be used on Lucky. However, it comes with the long barrel modification already added. It uses the least amount of AP of any revolver using only 17 AP. Furthermore, it is considered an improved holdout weapon and can be concealed and taken into weapon-free locations as long as one's Sneakskill is 50 or greater.
When player is reloading while running, the character may be stuck in glitchy animation after reloading completed for a few seconds or until aiming or firing to return back to normal animation. [已核实]
Giving Lucky to Cass or Raul causes a regular .357 model to be displayed on their persons, but giving Lucky to Veronica shows the correct texture of the revolver. [已核实]
If loading a saved game from the main menu in which you have Lucky equipped and drawn, the reload animation takes twice as long as normal. This can be solved by simply switching weapons and then back again. [已核实]
Using Lucky in V.A.T.S. may result in your character doing nothing for ~10–20 seconds, leaving you exposed to enemy attacks and unable to do anything during that time. It may be due to reloading and going into V.A.T.S. at the same time. [已核实]
When reloading in 3rd person view, the loading gate (the little piece you flip open to load the rounds) can become stuck open. This is simply fixed by firing or holstering and redrawing the gun. [已核实]
