Sure, there may be records of what you buy, but private citizens are not required to keep paper work for guns they may sell or trade - which is, coincidentally, what I did with all of mine - traded them for a table saw - to some guy I met at Dunkin Donuts.

Not nationally, but in some states (like here in CA) that would make you a felon, and inellegible to ever own a gun again. Here you would have to go to a licensed dealer and file a state transfer for each gun (about $75 per). I suspect WA may have a similar law.

[Psalm 73]

"....that would make you a felon...."

Soon we will all be felons anyways.
Like our brothers in NY state: "We will not comply".
If I could move to a Red state I would, but I can't right now - and appear to be just about out of time anyway. Then the whole country becomes a Blue state.

Washington State does not currently have a law regulating private transfers — but a bill with those provisions (but without home inspections) could, unfortunately, become law. Friends and relatives, however, will ignore it.
