I went/am going a different route: revolvers. Without all the linkages involved in semi-autos, I find the triggers in my revolvers to be second-to-none. Like, they barely move, and the hammer drops. I don't even find myself going all the way, in overtravel, and hitting the trigger stops.
They're not cheap, certainly--my S&W 617 cost a pretty penny, and I've been looking for a S&W 625 to go with it to shoot .45 and am gradually coming to understand that I'll probably need to pay about $700 for one, used--and to get that really nice trigger you have to do extra work (break your grip, reach up with the thumb, and cock the hammer), but they work for me.
