I don't mean to step on anyones toes here but let's use some common sense about this problem. I don't wear a dirk with an Argyle, I wear it with the PC. If I wear it with the PC I wear my kilt belt to suspend the dirk frog. If you're going to wear a dirk with the PC you simply wear the dirk with the PC and you suspend it from the kilt belt. If there is reason to wear the belt with a PC and vest what better reason than to suspend the dirk?
