Also if you want to accomplish the same elimination of the notch (with more cost, and much less sense of accomplishment), swapping in a Landon trigger bar will get you the same reset.

The notch in the trigger bar is set up to allow the firing pin safety lever to drop into the notch when the trigger bar is pushed down by the slide cycling. What makes the reset so much shorter is that the trigger bar doesn’t have to go back far enough to reset the firing pin safety plunger. With any of the “no notch” trigger bars (Langdon, silver soldered as above or the extreme S bar for the 92) the slide returns to battery on an unlocked firing pin (assuming you haven’t gotten off the trigger during the time it takes the slide to cycle).
Since this is the case, be very careful modifying the single action notch on the hammer, since hammer follow on an unlocked firing pin can be somewhat exciting.
