Also, one of the fellows I teach with, and who is very well trained and whose opinion I respect, likes Tactical Firearms Training Team
(TFTT). They put on classes various places, including Sacramento, CA.
And it looks like Massad Ayoob
has a MAG-40 (his first level class) coming up in Sacramento in May of this year. I strongly recommend this class, and if someone can take only one class, this would be an excellent choice. I'm not aware of anyone else who does as good a job of covering for private citizens the legal and social aspects of the use of force in self defense.
