How could he put four bullets through a wall when his hand was empty? The answer was that he had a pistol in his hand, with a round chambered and ready to go, before he was consciously aware of it. Though his employer would have bought him any sort of fancy gun and holster he had asked for, Sokolov had elected to stay with a Makarov: the standard-issue Russian sidearm, which was a smallish and rather simple semiautomatic pistol that lived in an odd and ingenious type of holster. Unlike most holsters, which were dead ends—you could only get the weapon out by pulling on it, butt first—the Spetsnaz holster was a sort of rail that the pistol moved through . When bad things were not happening, you inserted the weapon into the top of the rail, where it stayed, safe and secure. When bad things started to happen, you brought your hand down onto the butt of the pistol and pushed it down and through the end of the device. As you did so, lugs built into the rail engaged the slide of the pistol and pushed it back, chambering a round, so that by the time the weapon was free of the holster it was ready to fire. About a tenth of a second after the black man said " Allahu akbar, " Sokolov discovered his pistol in his hand in exactly that condition. He aimed it just to one side of the door frame and fired four rounds as quickly as that was possible while initiating a dive and roll. A burst from the AK-47 might have passed through the general area where he had been standing, but it was hard to tell; the apartment had become rather noisy, and all he could hear was ringing in his ears. He tumbled fluidly into the next space, which turned out to be a sort of back storage room, perhaps a pantry, with a sleeping bag, now empty, on the floor. The former occupant of the bag had gotten stealthily to his feet, picked up an AK-47 of his own, and made that furtive glance into the room where the black man had been mixing up the ANFO. Now he was slumped on the floor, not doing much. Sokolov could not see where bullets had gone through him, but he could tell from the sheepish, glazed look on the man’s face that he was hit. While making these admittedly hasty observations Sokolov began firing back into the room from which he had just escaped, but the black man had had the presence of mind to change his position and so nothing was there. Sokolov, now lying flat on his back in a spreading puddle of the other man’s blood, holstered his pistol and took the AK-47. It was a bit large and cumbersome for these environs, but its bullets would penetrate brick walls and it had a larger magazine.
