According to the RCW (Revised Code of Washington) which was amended due to I-594, specifically Title 9, Chapter 9.41.092, which you can read below requires a 10 business day waiting period if you are delayed during a NICS check. 
**************************************************
RCW 9.41.092
Licensed dealer deliveries—Background checks.
Except as otherwise provided in this chapter, a licensed dealer may not deliver any firearm to a purchaser or transferee until the earlier of:
(1) The results of all required background checks are known and the purchaser or transferee is not prohibited from owning or possessing a firearm under federal or state law; or
(2) Ten business days have elapsed from the date the licensed dealer requested the background check. However, for sales and transfers of pistols if the purchaser or transferee does not have a valid permanent Washington driver's license or state identification card or has not been a resident of the state for the previous consecutive ninety days, then the time period in this subsection shall be extended from ten business days to sixty days.
**************************************************
Evidently some gun shops never read this section and were still using three federal three business day waiting period.
SO................ Today I was at one my local gun shops. In walked some know it all. When the staff and I were discussing the 10 day waiting period he butted in an proceeded to go on about how all gun owners should have supported this law. He also went on to say that he voted for it.
SO............... He found a nice used gun which he wished to purchase. He filled out the necessary paperwork and paid. His NICS check came back DELAYED!
Guess how mad he got when he was told he had to wait ten business days?












Of course IF the FBI calls with a PROCEED before the ten day period, he can have the gun. If not, He waits. I hope he waits.
