Unfortunately M&P doesn't have any date/year marks on the firearm, nothing on the shipping box.
As
robrossk posted, I'd also suggest to call S&W, based on SN they will tell you year of manufacturing.
If you bought it NEW, my guess is - 2020. With today's demand you won't buy "old" new firearm
Also extra suggestion - don't post SN of firearms. Nothing against forum Members, but this information is accessible for ANYBODY !
