Actually there really are good drop in kits for 1911 style guns. They come with a Trigger, and then the hammer and sear have been stoned together. All you have to do is "drop them in"....as long as your frame in spec. They cost about as much as having a Smith, stone the sear and hammer, but they are true drop-in, and work very well. Brownell's used to carry them and probably still do. So in the 1911 they really aren't a misnomer
