The Colt you listed doesn't "sparkle" either. Go stand in the dark with a piece of chrome & see how much it shines. Of course the lighting is what's making the Glock 27's pictured shine. Nothing is going shine without light, Einstein.
Either you can't read or comprehend a sentence, one or the other. Because definition #2 stated, "to be bright with reflected light." Furthermore, when the Glock is introduced to light, such as a police officer standing 2ft away with a MAG flashlight, it is "bright with reflected light." ....thus SHINY.
