If the cylinder dimensions are the same as a listed revolver, then they might use the same speedloader. Whether your gun is listed or not , with the cylinder fully open there must be a straight path for all rounds to load simultaneously, plus a small allowance for the thickness of the side of the speedloader. If your revolver's grip or cylinder release is in the way of the speedloader, the grip or cylinder release may need to be replaced or modified. Make sure the round count of your cylinder matches that of the speedloader. Listed above is the extent of what has been tested by JetLoader or reported by other customers as working--if your gun is not listed we have no further information. NOTE: This ad is for ONE JetLoader.
