Adds a new pistol to the game, being a fancy-pants plastic-ass L5 Desert Eagle, for you to play around with. This particular one fills an interesting niche - being a practical utility pistol or another high-power hand cannon depending on skill investment and modification. It's also capable of hitting 32 concealment, in case concealment is something you care about. It's also fully-skinnable, and comes with a free weapon skin to show that off for you.
It also has customizable waifu grips, because I am a piece of weeaboo garbage. There's that too.
