At Crimson Trace they believe  you should always be able to sight and shoot a handgun without a laser. This new technology was never meant to replace your fixed sights, but to supplement them in difficult situations-like firing on the move or from awkward positions, defending yourself in close quarters, aiming in low light where iron sights are difficult to see, and any time that you're under stress. Under these kinds of conditions, our natural and automatic reaction is to focus on the threat, not the gun-sights.
