There are an endless amount of reasons to conceal carry, and not sure we could even figure them all out in one sitting. As your life changes such as getting married, having kids, moving to a new location, etc, you could have new or added reasons to ensure you can protect yourself and those around you with the best tools out there.
As with the rest of your EDC gear, it is all up to personal choice. There are experiences and outside forces that influence and steer why we carry what we do when we are conceal carrying. For me, my belt has been a journey and has a "story" along with the rest of my EDC gear. I have always wanted and been searching for the best conceal carry belt.
