HandIK Not Fully Working

I’m currently having problems trying to get my hand ik sorted. In short, the left hand follows the weapon socket of the right hand (for pistol) however it doesn’t fully “stick” to the pistol it just kind of… jitters and hovers around. On the two bone ik node, I have enabled bone space, take rotation from effector and maintain effector rel rot. None of this seems to fix it. The debug draw does show the same “hovering” translation within the rest of the joints so there’s something definitely going on. Any help would be amazing!
