An off-the-shelf parts substitution regarding the 92D reset might be with experimenting with the standard or extra-strength Wolff TCU, the Wilson Combat triggerbar, and the lighter Wilson chrome silicon mainsprings (perhaps the 13# or 14# ones-I'm a bit hesitant to recommend the 12# one for general carry, given that reliability seems to be a bit limited with it to softer-primered cartridges. That might provide a balanced, not excessively heavy triggerpull with a crisp (but not shorter per se, unless the triggerbar is appropriately modded {if that's indeed possible for this purpose}) reset.
