Where did Charlie get his gun?

Did I miss something or do we still not know?

He picked up the gun Jack dropped during the fight.

The real question is... how did he get so good with the gun? He's clearly used one before. To fire that many shots into Ethan and not hit anyone else who was standing around Ethan was really pretty impressive. Anyone think Charlie turned to actual theft in his addict days?

could be, afterall we just saw that he is a thief

I also thought he seemed awfully good with that gun. I was actually expecting to see something in his flashback about using a gun...
