Me-410s firepower won't get it perked, one fighter around it is enough to beat it 1vs1, unless someone decides to be in an I-16.
Look at the list of perkable choices, if anything the Me-410 sits between 5/10 eny.
If were going to perk the Me-410 due to firepower, then there are a dozen other aircrafts to consider perking like the Fw-190a8.
Yeah it makes no sense, so leave it alone.
