Oh no, '89 was very much a "transitional" year. Several Models as well as Models with mixed features eg. both "Classic and "MkII/MkIII" i.e. finish, sights, safeties, feedramp, FPS, etc. in a single Model abound.
You'll find the last of the MkII phosphate and the MkII matte paint over phosphate, the polished blue Vigilante ("Bump 'n Hump" and dovetailed MkIII sights), the polished blue Sport (original soldered ramp and the first MkIII "sharkfin" dovetail front sights), the phosphate MkIII, the matte paint over phosphate MkIII, the semi-gloss Epoxy MkIII, even...the first of the MkIII featured Silver Chrome Models...the Practical Model didn't appear until '90

.
I've got a total of seven '89s and they pretty much run the gamut...including a full MkIII feature plain phosphate "2864" where the original black cardboard box doesn't even mention "MkIII", as well as a full feature MkIII semi-gloss Epoxy like yours...even one of the Browning over FN slide legend MkIIIs, which is Epoxy over phosphate

.
Just another example of FN doing "whatever they wanted, however they wanted and whenever they wanted" with no regard what-so-ever to fools who must find order...where there is little
