College credit? Acquiring skills is more important.
That set aside, besides being a host to NRA summer gunsmithing classes, Lassen College use to (operative phrase is "use to") have a survival shooting course which and drawing, multiple target engagement, etc. Don't know if they offer it anymore. Check our link to the NRA for Gunsmithing Schools and you'll get a contact address for Lassen. I think Hayward State Univ. (of CA) also offered a handgun course (where you went out and shot revolver and pistol all the time) as some sort of self defense class. Ollie Samson use to teach it.
In CA, many POST certified police academies teach semi-automatic conversion courses (revolver to pistol or intro to pistol) which is 2-3 days long and got you half an hour or credit. Catch is for many you have to minimally be a reserve cop.
Many times it depends on the Community College and whether they're pressed for students. Some CC were dependent on military folks and their dependents and when the adjacent base closed, they scrambled for students and threw their doors open to many venues.
Check out Yavapi (sic) College which I think is in AZ. They may have something you're looking for.
