here in EU there is €970 ($1100) difference between S2O>S2
you get:
bushing
hand fitting
polishing
disconnector
hammer
orange grips (same as original)
left extended safety
orange mag catch (same as original)
orange base pads
a few springs and "better" pistol box
for that amount of money i would like to see more:
additional thinner front sight, fully adjustable rear sight, better grips (probably brass), sear cage fitting like in TSO, at least 4 magazines in box, more springs (main, recoil, trigger, firing pin), left and right extended safety, at least one backup slide stop (low profile), backup extractor, floating trigger pin, old style CGW 85C trigger, optic ready cut and bull barrel maybe
