Inspire by the what gun and ammo do you carry. How often do you practice with your carry gun? And how often do you use the ammo you use when carrying? I generally practice with my carry at least every other time I head out to the range, so once every couple months. As for carry ammo I do it from time to time, basically when I think about it and feel the need and even then it is usually only 5 rounds at the end of the day.
