Since no one touched on it, I will. There are two OTHER potential customer bases for this product: homicides and suicides. Neither would be very likely to do much repeat business.
I'm sure we can all imagine scenarios where those two groups would use something like this on impulse--annoying neighbor, barking dog (although that would be caniscide), nagging girlfriend or parent, or, I just lost the farm at the Indian Casino and want to end it all...I'm sure we get the idea.
What about the legalities? How do you go about, well...
1) Buying--there's a ten-day waiting period in CA and others in other states--how can we be sure the thing won't run out of shelf-life before we even take it home?
2) Registration--do you get a "T" before your registration number? How will the Feds differentiate between a "heirloom" gun and the throwaways?
3) Disposal--this ain't a Bic lighter, sonny, this is still a lethal weapon, although if it's worn out, which side is more lethal, in front or in back? Then, there's that pesky little number thing. I'm sure the BATFE has nothing better to do than run down a whole bunch of previously valid numbers and cancel them out. By the way, on whose say-so are they doing this cancellation? Local cops? Well, they're pretty busy right now, answering shooting calls. The buyer? Right, I've some Blue-Sky stock you need to look into if that's what you're thinking. Oh, now I get it--you're going to add a whole 'nother layer of bureaucracy.
Imagine all the jobs to be created. First, we've got the R&D fellows just developing the product, then the tool and die guys, then the production guys who geared up to meet a demand anticipated to be ten times that of normal firearm production, then all the clerks who're gonna sell this thing, then all the paper-shufflers who pick up then cancel the registrations, plus all the guys who are actually responsible for the receipt of, transportation, break-down and disposal/recycling of the product's components. And all this doesn't include the three or four levels of management needed to oversee this whole magilla...
By golly, you may have solved the recession!
