Weapon Trade Glitch

So does this work in Suba?
I heard the steps to be
1. Press Sort

2. Put BD weapon inplace of a trade-able weapon

3. then open the trade window

4. choose the trade-able weapon

5. press sort

6. press trade

This has been failing for me, keep on getting weapon error 4.

Anyways shout out to whoever figures it out. whisper me pls

so, you wanna trade an un-tradeable weapon ?

Well its been done. I know they fixed on GC but maybe not on Suba. But I sense sarcasm, pm me if you for real though.
