"At night, or in Seattle, I might carry a reload or two and a Surefire light, but that's if it's a full moon and I'm feeling nervous. I pretty much avoid anywhere that I would plan on needing a gun in the first place, so I usually don't bring a reload everywhere with me. However, I keep 2 loaded mags in my car, so I'm never far from a reload."
I agree with 99% of your post; hence the reason I travel light. However I carry an additional mag on my person since there have been documented instances of mag-induced stoppages, and since I carry a pistol with a seven-round mag. But at the risk of hijacking this thread, that may be the topic of another thread.
