The Walther NightHawk is an air pistol that has so many features and accessories that you'll be ready for anything. It has a side-mounted flashlight that's activated by a switch on the grip, a red dot sight with 11 different brightness settings, and it's has a CO² repeater, which means it'll fire its eight pellets as fast as you can pull the trigger. If that's not enough for you (the world is not enough, after all), the NightHawk has four rails on it for accessories, including stuff such as scopes and speedloaders.
The Walther NightHawk air pistol goes for $160, though you can't buy one if you're in NYC, I notice. I guess we just use the real deal out here.
