I’m curious. What are the advantages of Gen 3 pistols over Gen 2? I get the big jump in going from Gen 1 to Gen 2, but what’s the benefit of the next factory revision?

Mostly, the difference is in ergonomics. The gripping area under the trigger guard allows for a slightly higher hold and you get a better and more comfortable place for your fingers. The one-piece wrap-around grip makes the pistol slimmer and this is a big upgrade for the double-stack pistols.
The sights also got better. If you have the big gangly adjustable rear sight, it didn't change a lot but the front is dovetailed and drift adjustable and swappable. If you have the rear fixed sight, the Novak lo-mount was a tremendous upgrade and it is also replaceable with night sights. No snag and most will agree that it's a lot better looking too.
The finish is different, not a bright stainless like 2nd Gens but a bead blasted matte stainless. You can argue the utility of this, but it certainly is different.
The magazines evolved a bit, the double stack 9mm mags gained a larger, ergo-friendly plastic base plate and gained one round capacity. The single stack 9mm mags did exactly that also, but it isn't specifically defined WHEN they each gained a round.
Later 3rd Gen pistols moved to a MIM hammer and trigger, and although it is often like asking "Ford or Chevy?" in a gun forum,
real S&W pistol enthusiasts know, or eventually learn, to forget the argumentative nonsense associated with the scary MIM label. MIM is like a lot of things... done well, it's fantastic. Done lousy and it's junk. S&W MIM is exceptional and in the case of 3rd Gen pistols, the MIM hammer and trigger almost
always results in a smoother trigger pull in DA and a cleaner pull in SA, and a better trigger all around.
We can debate it, but I own eight 1st Gens, eight 2nd Gens and thirteen 3rd Gens and 2nd Gen triggers are the WORST across the board. Worst DA trigger and it isn't close, and the single action is also the worst of the three Generations. Certainly, exceptions exist. By and large, the 2nd Gen triggers are worst.
There is a lot of debate in this, so it is with some trepidation that I make bold statements as I do, but I can only tell you that I do it with hands-on experience, enthusiasm and genuine love for ALL THREE generations of these pistols. Please read that again -- I have a lot of love for the 2nd Gens and they bring interesting angles to the discussion, but it doesn't change the realities of their guts and how smooth their guts are.
1st Gen pistols benefited from old school real craftsmen that had to put them together and make them great. 3rd Gen pistols benefited greatly from advanced parts manufacturing that made a huge difference in the tolerance of all the interacting parts. And the 2nd Gens were stuck in the middle... new upgrades such as the firing pin lock and high volume production, the fitment and smoothness is lacking in the 2nd Gens and this is reflected both in their popularity and their market prices.
