My answer is yes AP and yes +1harm, straight up.
djmalloc, it's just because gangs' weapons work differently than individuals'. When you stat up a gang, you don't look up stats for its weapons in particular, you decide broadly and overall how good they are. I decided broadly and overall that the gunlugger has good weapons.
When you MC, you can have the NTBFW gunlugger use her actual weapon stats instead, if you want. Technically that'd be a custom move on your home front, but you probably wouldn't even bother writing it down.
