I use canvas M2 50cal cleaning pouches for my P68SC:

I got em 4 for $10 from the sportsmans guide, but they don't have any more.
M2 Browning MG .50 Caliber has them as
C64274 Cleaning Rod Canvas Pouch (M-15) $5.75
They have top and bottom loops on the back and a belt loop, so they work as a back holster or hip. Not as nice as better materials but a cheap and handy backup.
