ATF statistics for 2007 published
The Bureau of Alcohol, Tobacco, Firearms and Explosives have published Annual Firearms Manufacturers And Export Report 2007 (warning: PDF Link).
It gives some interesting insight into firearms sales:

Pistols Manufactured in 2007

Revolvers Manufactured in 2007

Rifles, Shotguns and Misc firearms Manufactured in 2007

Exports in 2007
Interesting facts:
5.01% of rifles manufactured were exported in 2007.
3.7% of pistols were exported
8.7% of revolvers were exported.
32% of pistols are 9mm (presumably 9mm Luger/Parabellum ).
All 9mm calibers (including .380) came to 43% of all pistol manufactured.
23% of revolvers are .22 or below in caliber. Likely to be mostly rimfire.
Because the BATFE do not breakdown the distribution between calibers 9mm and .50 we cannot compare .40 S&W and .45 ACP to 9mm Luger.
Thanks to Jay for letting me know the report was published online.
This is good stuff Steve,
thanks for sharing,

I’m not so sure about those figures… 452,185 .50 cal pistols?? What, Desert Eagles? I don’t think so…
Would it be fair to say that neither .40s&w or .45ACP outsold 9mm?
Long_Shooter, 452,185 is the number of pistols manufactured with a caliber larger than 9mm including everything up to .50 caliber.
Gentlemen, that is TO 50, not 50 caliber, so just deduct the ones below from the new number.
Hope that helps.
