When I went to S&W the MP10 Sport they have listed is at msrp $1049.00.

By appearances looks pretty much like the one I got except the sport has a 16" barrel vs 18" and it has a different flash suppressor. For chuckles I clicked "buy now" and when I went to the S&W store it was listed "out of stock".

Typical of most companies is to spin the marketing section up to start advertising before production kicks in.
