Sometimes I wear jeans without sufficient space to slip a Sabre Red MK-6 in the pocket. The clip is worthless OWB. One just slippped off my belt before I ever even left the house.
I recently found the Depring magazine pouches on Amazon for about $7. By cutting off the MK-6 clip, the Depring pouch makes a perfect OC pouch for the belt. Snake Eater Tactical offers something very similar I use for my G43 mags.
