Howdy,
Got this belt slide from Cabella's which holds a pair of spare Remmie cylinders perfectly.
Do a search for...
Triple K Double Leather Clip Pouch Item:IG-226413 $19.99
It's designed for Ruger 22 caliber auto loader rotary magazines. These happen to be about the same size
as Remmie NMA cylinders. Nice snap closure and a little hole in the bottom to help push the cylinder up out of the pouch.
Slide it onto your holster belt, drop in your pre-loaded cylinders and you got speedy reloads for your Remmie !
Cheers,
Cincinnati Slim
