The Thunder 5 is overly heavy and bulky and has NO advantages over a standard .44, .41 or .45C. It is inaccurate at even short ranges with both calibers, the .410 out of a 2" bbl is not a significantly better "scattergun" round than shotshells. The 2" bbl is too short for any decent velocities or accuracy with the .45 plus it's noisy and massive flash to boot.
You won't find many gunsmiths who will work on it and finding a quality holster is gonna be a search.
It's a novelty and a solution in search of a problem. Take the alternative solutions offered above.
Here's how it works on a public forum: FIRST, you say something that establishes you as someone to be taken seriously. THEN, we'll spend time trying to extract what you might mean, if we think it's worth it.
So far, it doesn't look promising. - dgg9
