When "hold-breath" is activated with the v-stock, immobilize the front hand, and let the user aim with their rear hand. This would more closely simulate a bipod, and it would be more intuitive, because the hand of the trigger you are using to activate hold-breath would be the same hand that gets stabilized.

Currently, it works in the opposite way: activating "hold breath" with the v-stock turned on freezes the rear (trigger hand) and make the user aim with their front hand.
