I like the concept, but it's been tried before without much success. Handgun hunters have too many choices for a single shot 45/410-22 to be a good seller. A 454Casull/410 shotshell may have been a better choice to appeal to hunters. A second barrel in a rifle caliber would have also been a better choice than 22. How about 22WMR, or 223, or even 30-30? If you're going to compete with TC, jump on it with both feet.
