"about 158,000 were in .45, or about 45%."
That's the figure I've heard, as well, but of those, a significant portion went to the US Army and some I believe went to the Navy (not many).
OK, I just found some information that says that the US Gov. took about 37,000 of the .45s, so that would still handily leave it as the most popular chambering in the civilian market.
