The ShopKeeper is a cute gun as is, but I could have lived with an extra 0.25" of barrel length, and I think it would have looked just as good, and balanced just as well. Ejection of cases would have been greatly enhanced.
I have learned to scrape the ejector against the chamber wall to catch the edge of the case mouth when ejecting fired rounds, but it should not have been necessary to do so.
