agree with krayzhorse ... more a seasonal thing than a time-of-day issue ... I pocket carry almost all year, so the size of the gun I carry is limited ... when it's cold and I can wear a cover garment, I tend to carry a larger (still 9mm but with lots more ammo) on my belt ...
"The gun has been called the great equalizer ... It insures that the people are the equal of their government whenever that government forgets that it is servant and not master of the governed." --Ronald Reagan
