Wow. Somebody must have been a captain..or a chief.
I qualify quarterly. (For those of you alarmed by the article, that means FOUR times each year.)
Between qualification and training I shoot about 200 - 250 rounds on a training day.
That means I use about 1,000 rounds of .40 a year. Contrary to the linked article, we only shoot our carry ammo. Wasteful, yeah I think so, but that's how we do it.
CJStudent already mentioned FLETC. He didn't mention that there are several FLETC locations:
FLETC International (Hungary, Thailand, Botswana, and El Salvador)
On top of that here are the majority of gun-toters that fall under the umbrella of DHS. This doesn't include DHS-OIG and I didn't include the U.S. Coast Guard. I know they carry the Sig P229 in .40 also.
