So the ingame model of the MiG-29M is just a reworked MiG-29A which, you already went through the trouble of changing it for the intakes and wings, but you overlook the countermeasure system, MiG-29M didn’t have the same vertical stabilizer extention with countermeasure dispensers and you can see it in multiple pictures:
You can see it especially here, this is the picture of the demonstrator MiG-29M no. 156, which gaijin also used for one of the camos and you can clearly see the lack of the countermeasure system, you can see how the vertical stabilizer is very similar to the MiG-29K (Which gaijin did model properly)
You can see here a MiG-29K for reference, notice how this also doesn’t have the vertical stabilizer countermeasure extension.
Furthermore you can see on other pictures of the MiG-29M where the new countermeasure system is housed, this holds smaller caliber countermeasures, this is made for compatibility with export systems and it can hold twice what the current MiG-29M load is, which would make the 29M more competitive at 13.7 and more pleasant to play since it faces mostly ARH missiles (Also make it look better imo cause the cm extensions just don’t look right on it but that’s just me)
Lastly the MiG-29M could use the same counteremeasure pod system that the SMT has so that would be a nice addition as well giving it some more options to take flares/chaff for fights
