So you are shooting Revolver Division in the SSR sub-division. Your revolver is chambered for 6-rounds. On your belt you can carry three speed loaders in pouches. Since you strong hand load, you can have two in front of the holster (and they must be within an inch of the holster and each other) and one behind the holster. You could have a fourth (behind the holster) just to hold the loader that you will charge the revolver with at the line, when given the load and make ready command (24 rounds total). Holster must carry the gun with the front strap of the grip above the top of the belt and it can be no farther forward on your belt than the mid-point of the trigger on your body center line.
Adios,

PS: If you are penurious like me, you can save some bucks by using an HKS speed loader (about $10) to do the initial charge at the line and save the Comp III's for loading on the clock. I usually just carry the initial loader in my hand or pocket.
