Mossberg 500 "Chainsaw"

This is actually real and can be seen on Mossberg's website (here, and then scroll over a few images)., and up for sale on Gunbroker for under $400. Really a standard Mossberg 500 with a weird chainsaw pump. Silly marketing idea come to life. There's a lot wrong with this...pistol grip, awkward to hold, awkward/not practical to aim, awkward to pump, the chainsaw grip adds extra width and would make it awkward to carry slung or in a case...could go on, but you get the picture.

It's totally impractical; if someone wants to buy it for a range toy, then whatever. But for anything serious, this is a poor choice. What do you guys think?
