Washington State is a "shall issue" State. They have to as long as you're not a criminal, or domestic abuser. Within 30 days of application. We recognize any other State's license as long as their requirements meet our background check requirements, and they recognize out of state licenses themselves. I believe currently the list is Arkansas, Mississippi, Ohio, Florida, Missouri, Oklahoma, Louisiana, North Carolina, Tennessee, Michigan, North Dakota, Utah.
Used to be a really fast process. Now I hear they take the full 30 days due to staffing cutbacks. Less paperwork than the federal firearms form, but fingerprinting is required of course. No classes or training required.
So I can pack my gun, but I'm in violation of the law if I carry my Spyderco Endura with its super scary 3 and 3/4 inch blade... I carry that knife in the field when hunting or fishing, but I'd never carry it in say Seattle... I carry a dainty 3 inch delica in Seattle to not frighten the dazzling urbanites... And a 4.5 inch barreled 45 acp M&P
