A multi material dispensing gun that can receive high pressure different materials therein, keep the materials separated, and then simultaneously dispense the materials therefrom. Valves are positioned in the gun to permit leading seals of barrier fluid chambers to be subject to the high pressure only during gun dispensing. Dispense pins control opening and closing of the valves. A manual trigger can be used to control movement of the dispense pins via an actuator arrangement. The valves, dispense pins, and barrier fluid chambers are part of a replaceable modular gun segment. This segment is removably connected to a dispense segment that includes the material inlets and dispense outlets.
