Ok, I'll give you that.
They'll have whatever requirements there are for CCW in their own state, which may or may not include training.
I think the federal CCW law would have more support if they included a training component. The problem arises when those training standards are being discussed. Who decides on duration, content, amount of live fire, grading, etc? Can't make it too tough, because it'll deny you a constitutional right. Can't make it too easy, or it'll be a waste of time.
Maybe a blanket statement that there must be some CCW training to include familiarization with use of deadly force, federal and local laws, live fire skills, proper safe handling and holstering/drawing, and other basics any gun user should know.
In short, an NRA-certified CCW class. Leave it at that, and trust the NRA to make the courses not only adequate for safety, but also consistent nationwide.
Just a thought.
