The most recent publicly available data is here at the link already provided, unless someone here has connections at all three companies (two of which are publicly traded) that are willing to divulge more recent and granular sensitive business information.
Also, I'd beware of linear extrapolation. For instance, Kel-Tec's 9 and .380 are priced similarly but disparate in size, whereas (at least in 2011) Ruger and Smith offered a single .380 and a broad range of nines, in Smith's case running to several multiples of the price of the .380.
