It's been a while since I've playtested the fight, and I don't think I ever bothered to beat it, as multiple players reported they were able to. I may revisit it eventually, however it should be doable, although punishing. Remember to take the clips off, if you aren't. That buys a lot in terms of damage and time. Beyond that, it's really a matter of crowd control: if you get to the point where there's a ton of enemies on screen, you've probably already lost. I'd imagine some save scumming to try to get ideal luck with where "Hard Knocks" lands would probably do it though.
