I had a local holster smith make a kydex holster for mine as well as some moonclip holders...will hold 4 loaded moonclips on each for USPSA Revolver.
Before that I used a Kramer Revolver scabbard...still works fabulous for me!
IDPA is different in what is allowed for extra ammo. I usually use just one of the carriers, although I did find that HKS speedloader pouches work very well for me.
