3/6/14 Update: The issue with the Gusenberg Sweeper missing from the weapon inventory has been resolved. In order to re-enable access to this weapon in your inventory, you'll need to reboot GTAV and load back into GTA Online with each character that previously had the weapon in their inventory. So, if you have more than one character that had the Gusenberg, you'll need to repeat this process of rebooting the console for each of your characters. You’ll also need to go to Ammunation to re-apply any gun mods you had for the Gusenberg, but you will not be charged again for components you had already purchased.
