It's not too far off, when we weighted a 105 5800 group set in the shop for a customer:
Shift Levers - 485 grams
RD - 236 grams
FD - 91 grams
Crankset (50/34, 172.5) - 740 grams
Cassette (11/28) - 284 grams
Chain - 255 grams
Brake Calipers - 380 grams
That was 2471 grams with no BB or cabling. I forget the final weight with the cabling but it was absolutely over 2500g for a functional 105 5800 group set.
