The SW 500 is chambered with the BigBurger Inc.-standard 8.9mm Fragmenting Flechette, the first weapon to use this unusual round. Control is excellent, and the high wound potential makes it a good weapon for close encounters. Deirdre Lux made one attempt at modifying the standard MTI SW500, it was hardly surprising that it outclassed the Chapman completely.
