2011 is a made-up name for a gun (or line of guns) made by STI; essentially a squared-off. chunky, futuristic looking double-stack 1911. As far as I've seen, no other "real-steel" manufacturer refers to their double-stack 1911 products as 2011s. Try Googling "2011 guns" and the first page will only reference STI or airsoft guns.
Sorry, it just bugs me, all the talk of "Hicapas" and "2011"s. These are model names for a few specific items that seem to have become catch-all terms, like Kleenex instead of facial tissue, or ***** instead of photocopier.
