Seems like this would be a no brainer since the short double with a cut down "birds head" stock is more or less the iconic "sawed off shotgun"/"lupara"/...

Not really any more practical necessarily, but I'm just suprised that I haven't seen anything along these lines. Especially with how popular these bang sticks are in movies.

Considering the price point of doubles these days, most of the existing lines would be too expensive. But I can't believe lower tier manufacturers aren't cashing in.
