I used to carry a horizontal mag pouch at about 1:00, in the empty space where speedloader pouches went, when we had revolvers. Tops turned toward the belt buckle. It is comfortable, fast to reload and you can reload while sitting in a car, if it ever comes up. It also allows more space on the left-hand side for flashlights or whatever.
The person who has nothing for which he is willing to fight, nothing … more important than his own personal safety, is a miserable creature [with] no chance of being free unless made and kept so by the exertions of better men …. John Stuart Mill
