Lately, I've been carrying an extra in my cargo pants pocket. If I'm not wearing cargo pants, then I usually won't carry a spare. Most mag pouches are pretty uncomfortable. However, I just ordered, and it should be here today or tomorrow, a horizontal mounted mag pouch that's supposed to be worn at around the appendix position on your weak hand side. I'm hoping this one will be more comfortable and I'll actually use it rather than the half dozen or so I have that are in my drawer collecting dust.
