In that case, you must not know any custom 1911 smiths used by any serious competitive shooter, because I can give you a laundry list of people who do so, and literally everyone who is winning (and probably everyone within the top 10-20) the Open/Limited/Limited Optics/Limited 10 nationals is using a gun with a 2 pound or less trigger from one of those people. In IDPA, the winners in the Carry Optics and ESP divisions are doing the same. Unless your "action" sport is something besides USPSA, IPSC, Steel Challenge, IDPA, and maybe some I'm forgetting, literally everyone who is winning is shooting something you didn't know existed until you made these posts in this thread. And many are using 15 pound mainsprings because they want the absolute lightest trigger, and the only way to get that is with perfect sear geometry, the right sear spring tuning, and the lightest mainspring their primers will tolerate. Maybe it was different 50 years ago or something, but these sports are incredibly competitive, and the winners will do anything to win, including using trigger pulls lighter than the gun that is in their hand, among other minor equipment advantages to have every competitive edge. And there is nothing wrong with that, as if the guns are kept clean, a 2 pound trigger is absolutely reliable in a 19/2011, it just needs to be in the hand of someone responsible enough to keep it that way.
