Converted animation issue with gun movement

[biridius]

Converted this model.
For some reason the gun motion is off in some animations.
Flies away in odd directions.
I'm not sure what exactly is wrong with it. Is it the Z-up / Y-up swap bug? Or is the gun supposed to be attached to both hands somehow?
Any thoughts?

I tried running the translation animation through my axis swap script which worked fine for the main root bone, but it didn't work out for the gun bone. I guess I'll try adding more swapping options to the script because it looks like an axis swap bug.
