No, not almost, if you're going to speak to the general public, speak in terms they understand. Go look at any of several hundred "triggers" for sale on Ebay, or just about anywhere else, a trigger for sale isn't the trigger shoe, it is the trigger unit/assembly.
Or better yet, why don't I sell you a Stage III trigger for $125, I'll pick up the freight, because a $0.39 stamp is going to cover sending what you will get.
