Rotate bone alongside with another? [Solved]

I'm trying to create an offhand attack animation which would require the re-positioning of the hp_weapons bone. In other words I would need it to follow the movements of the left hand rather than the right hand. The problem is that every time I rotate the two bones one bone (hp_weapons) starts moving to odd positions, ruining the attack animation.

What I've done:
1. Moved hp_weapons to the proper position on the left hand.
2. Rotated and moved the two bones together
3. Keyed the rotation/movement a few frames after the previous.

Result:
Rather than following the left hand, the hp_weapons bone follows its own path during the gap between keyed frames.

Is there anyway I could get around this issue without keying every frame one by one?
Thanks in advance.

Translate hp_weapon to the left hand (maintain original hierarchy) then pose constrain it to the left hand bone and animate however you want, then plot and export.

Every time I pose constrain the hp_weapons bone moves to the exact position of the hand null, am I missing something?
What do you mean by "plot"?

Enable constraint compensation (CnsComp) to prevent hp_weapon from jumping during setup, disable it afterward.
