Well, if you know that .22 target revolvers (with the 6" barrel) were carried by the auxiliaries, fine. There will be a unique RCMP issue holster for them in that case, because they certainly would not fit any other issue revolver holster.
The local RCMP detachment had a K-22 in its inventory (NOT auxiliary issue). Reasonable shape but much more used that the BC aux. ones. No holster for it. Last I heard, it had been lent to the detachment in Pangnirtung.
