A free mod for Cyberpunk 2077, by SKNTheLisper.

Discard magazine ammo on reload is a free app for your Cyberpunk game. It lets you use the game’s built-in functions to remove the strange magic that V has to reload his ammo. 

With this mod, you can also choose to disable the ammo-discard option, which will cause the game to behave the same way it does in the vanilla version. You can also choose to delay the time it takes for the ammo count to update, which is an option to make the app more stable.
