Trying to create a James Bond car, but having trouble with the machine guns....?

Okay, so this is my problem:  I'd like to operate two of the mini m-16 style airsoft full automatic guns using the trigger on my old salvaged joystick.  So what I have done so far is purchased a battery box for four D cells with the thought that since each worked off of four AA batteries, the larger batteries would run both and they dowhen I connect the wires directly from the battery box to the two guns.  The problem comes when I try to use the button as a switch.  I've already used a continuity checker to verify that the switch is working and from the correct wires, but when I put the switch in line, all the guns do is make a faint strain sound, like the guns aren't getting enough juice for the motors to run.  I've taken apart the joystick and the bottons are very much like the ones I have here shown on the cuircit board, they are like the ones in the base sets of old wireless telephones and such.  So if I'm correct, the switch is limiting the amount of electricity going to the guns so I was thinking about using the joystick to operate a relay that connects to the battery box maybe but I'm totally lost when it comes to which relay to use, where to get the relay, if this will even work, etc, also I was thinking about running 12v car accessories from the other buttons so how might I do that.  Thank you very much in advance, I love this site!! : )

Joystick switches and cables are only designed to handle small amounts of power.
If you've got 4D cells, that says 6V each to me - wire both guns in series from the car's battery and switch with a 12V relay. The joystick might manage to power that.
