My movie line generator went into motion when the OP said the would be assailant began calling him cowardly and a weakling...

Thankfully I live in Arizona, where we have a law called Defensive Display, which specifically states what he did, even up to drawing to a low ready, is 100% legal when threatened with physical force. With the legal disparity of force of size and training,
using only the facts as given, it wouldn't be too hard to upgrade the threat to Deadly Physical Force.
Of course, I am not an attorney, nor do I play one on TV.
Sounds like your man played it well.
