Not into Trap, but
Have you check out Kesselrings in Burlington? They usually have a lot of different shotguns and stuff in there, and if you are looking for something particular you can tell them and they will call you if something comes in that they think you might be interested. There is a new shop in Anacortes just past the Swinomish Casino at the top of the hill too, might be worht checking out if your around the area.
