Don't worry. Your guns are minor things for which what happened to Will. His whole business is gone. His job is gone. All the money he has invested into SpecArms is gone. He's probably clearing things up... Hes been out and around, I know for one thing he was at Hot Import Nights.
I'm not sure what hes doing but probably he is trying to relieve his stress from the whole "Seizure" that happened. He's probably pretty shocked about what has happened.
Don't worry about your gun. I'm sure he has something planned to repay or get your gun back. Will's a good guy. Give it a month or two for things to be sorted out. Dealings with the government can be VERY slow.
