Very odd 1911 configuration, almost as if somebody had made a newbie a "deal" on this thing when the newbie didn't want to pay Kimber, Les Baer, Ed Brown, etc... prices. I can't imagine anyone who'd had a 1911 that long to not know the difference between a .40 S&W and a .45 ACP cartridge almost instinctively.
You OK bud? :)
