Does having a light and/or a laser on your personal protection firearm make a difference in low-light conditions? How about no-light conditions?

The latest concealed-carry pistol from Springfield Armory is the small, thin XD(S), which is now offered in 9 mm Luger, and we evaluate it this week as our "Rifleman Review." The Walther PPK/S is a gun that was created in response the Gun Control Act of 1968, and we look at it as this week's "I Have This Old Gun."
