$400? I think I'd use the money to buy another gun instead. Not sure how the color would have an effect on battery life.I just bought my first Glock, Gen 4 19.
Im thinking about A green Laser Max guide Rod, Ive heard some up's and downs about them but wanted everyone feed back before dropping @ 400$
Green they say is brighter and extends battery life. Local Gun shop guy says company is great for support
