If you are sure you want to take them off, you need to carefully (with the exact size screwdriver) turn the one screw to start to loosen the sidelocks. about three turns, tap on the left sidelock with a non marring hammer. that will start the right one to come off. take the screw the rest of the way out and complete taking the right one off. Remember they are chamfered at the front end. Then take a dowel and place in the hole to gently take the left one off. To replace them, you may have to tickle the trigger blades a little, sometimes you have to send them in to have the blades adjusted slightly. That's why I caution just make sure you really need to take them off.
