We are happy to recommend Sporting Systems

They have an excellent free firearms safety course.
I highly recommend watching the videos as they are well done.

As part of new Washington State laws that went into effect, purchasers of firearms need to complete a firearms safety course every 5-years. This course will allow you to print out your certificate and complete the required training.
