I recognise the benefits of unarmed combat skills, but personally it comes down to prioritization for me:
I don't have a lot of time on my hands: I work full-time plus studying after hours (and I'm married , which comes with its own responsibilities), so I really have to choose carefully what I am going to focus on. Personally it makes more sense for me to spend the scarce free time I have mastering handgun techniques and drills, as opposed to trying to squeeze unarmed combatives in there too. My EDC handgun is afterall what I consider my primary weapon, and I am paranoid about maintaining (if not improving) my proficiency with it.

Perhaps I'm looking at this wrong, but then again that is what a forum is for: debate.
