1. A method of functional grip fitment, comprising:
receiving a user forearm in a forearm cradle configured to provide dynamic support and alignment thereto;
receiving a first portion of a functionally gripping user hand at a lower grip operatively aligned with the forearm cradle and configured to be normally grasped by a middle finger, ring finger, and little finger of the functionally gripping hand, and configured to adjust position with respect to the forearm cradle in response to a positioning of the functionally gripping hand;
receiving a second portion of the functionally gripping hand at an upper grip operatively coupled to a top portion of the lower grip and configured to be normally grasped by a thumb and trigger finger of the functionally gripping hand, and configured to determine via a curvilinear surface a circumferential grip distance associated with the thumb tip, thumb crotch, centerline of trigger finger distal phalanx and trigger fingertip of the functionally gripping hand;
receiving the trigger finger of the functionally gripping hand at a trigger adjustably coupled to the upper grip, and configured to determine via adjustment thereof a trigger finger length of the functionally gripping hand;
determining, in response to a dynamic trigger finger pull force exerted on the trigger by the trigger finger of the functionally gripping hand, a trigger finger pull force of the functionally gripping hand; and
determining a handgrip fitment using the determined circumferential grip distance, trigger finger length, and trigger finger pull force of the functionally gripping hand.
