2 in shoulder holsters, 2 in strong side holsters, the last 2 in saddlebag holsters, that gives you a place for extra ammo.
2 in shoulder holsters, 2 in strong side holsters, and the last 2 in chest holsters.
2 in shoulder holsters, 2 in strong side holsters, and the last pair stuffed into your boot tops.
