"The backyard guards were easy. Bolan found them smoking on a patio behind Bahaar Jadoon's house, underneath a yellow light designed to ward off flying insects. Trusting in the light to spoil their night vision, he cut the chain-link fence instead of scaling it—less noise—and tied the flap open with twists of wire to make it simpler for Gorshani, bringing up the rear. When he was thirty feet from contact, still outside the pool of yellow light that bathed the patio, he drew the black Five-seveN pistol. Even with its fully loaded magazine, the gun weighed barely a pound and a half, thanks in equal part to its plastic grip and the fact that its twenty 5.7 mm rounds weighed only half as much as standard 9 mm Parabellum cartridges. Recoil was likewise reduced from the typical niner, despite the 5.7 mm's powder load, which enabled the bullets to penetrate Kevlar. Also, like the military M-16 projectiles, they were designed for maximum internal damage without a hollow point round's expansion or the explosive fragmentation of a frangible bullet."
