Bug? Stuck in "The Gun"

I'm on a mission called "The Gun". I went to a gun shop, met with Wilson, followed him into a shooting range. Now I'm stuck. It says "get your gun from Wilson" but he does not respond or do anything. I can't leave the room. I've tried restarting. No luck.

Please tell me there's a way out, or I've lost my entire game, and there's no way I'm starting over.
