If you are looking for a holster for the larger diameter barreled PPC revolvers you can make a simple modification to the Safariland 002 holster. Loosen the two screws at the barrel end of the holster, place the revolver in the holster and tighten the screws as tight as you can, without striping them. Use a hair drier or heat gun on the area of the holster around the barrel. Get the holster hot, but be careful, if using a heat gun, not to melt the holster. let the holster cool completely, and then loosen the screws and remove the revolver. Adjust the screws for the amount of tension you prefer. This has worked well for me, and the plain kydex seem to work better.
