It feels more like refinement than any kind of revolution. We're seeing better ergonomics and triggers but nothing that completely changes how we actually shoot.
I will say they are small steps forward than any huge jumps these days. We're getting better ergonomics and triggers but nothing that totally changes the whole game for me personally.
Mostly cosmetic with occasional genuine improvements buried inside. Optics cuts and improved ergonomics matter but the fundamental pistol hasn't changed much since Browning figured most of it out.
