Easy, Quick, Simple, Effective (Hell in a Handbasket)
One reason that firearms are absent from most martial arts is the same reason that firearms are absent at piano lessons. They aren’t related. Most martial arts are older than commonly available firearms, thus guns are just not part of their traditions. We assume that martial arts are designed to fight-off modern muggers rather than the muggers of ancient history.
Another reason is ignorance. Many martial arts instructors spent a lot of time on learning their art and don’t really know anything about firearms.
I don’t believe it is economic. Most martial arts schools are hobby businesses that don’t really provide a living for the instructors. I know a few people that are highly ranked within their systems and teaching is still a labor of love rather than a profit making enterprise.
Finally, while firearms are “easy, quick, simple, and effective” they are not applicable in all situations. A non-lethal threat that doesn’t respond to pepper-spray is going to require some other skill set to deal with. Martial artists who believe they are teaching self-defense are wrong not to cover firearms, but Shooters are wrong not to cover unarmed skills.
