Abstract: A firearm handgrip assembly with laser gunsight system has a frame, a laser element movably connected to the frame, an adjustor connected the frame and operably connected to the laser element to establish an aiming direction of the laser element based on a position of the adjustor, and an elastomeric restraint element contacting the laser element. There may be a spring other than the elastomeric restraint element and configured to bias the laser element against the adjustor. The laser element may be pivotally connected to the frame. The frame may define a laser element chamber configured to receive the laser element and may include a door configured to enclose the chamber. The door may include the elastomeric restraint element. The door may include a thermoplastic body, and the elastomeric restraint element may be connected to the thermoplastic body. The elastomeric restraint element may be chemically bonded with the thermoplastic body.
