probably not since here is how the ending ID for weapons go:
3 = low normal
4 = med normal
5 = high normal
6 = refined
7 = unique
8 = elite
9 = super
And the only avaliable IDs if you were to go around 410200 would be
1
2
Which have no potential quality =] (I also say this because i cant find 410200)
Soooo these are the poisin weps:
410050
410060
410070
410080
410090
410100
410110
I believe when u upgrade them it keeps the poisin and goes to the new quality aka
8
9
Same concept for upgrading the level, i could be wrong because I havent checked this im just going off basic knowledge.
