I've done light dueling for fun at home and its fine. The graflex is made for dueling due to the screw on grip section but like most things it depends how it was installed. The button would have to be secure to the switch and the chassis would have to be solid. The Padawan is probably the best chassis to use but I use my master chassis lol. If it has any problems I can just rebuild it myself. The OWK might have the red button get knocked off if youre not careful though.
