There is no "proper" SxS shotgun. The best thing to do is to fly to London, Northern Italy,.....and have one crafted to individual dimension and intended use. Custom fitted footwear and attire is usually ordered at the same time. Basically what I'm saying a shotgun is just like made to specific feet pair of shoes. No worries for those that can't do that if they pray real, real hard it is said they will go to magical place or come back as people who can make the trip for them guns and proper attire.
