I did at first, but I'm equal parts form and function. With the adapter, it was 20-80, respectively. As long as the cartomizer in that cartomator tank isn't flanged, there shouldn't be a problem and your p+ will fire like a champ. If it is flanged, the cartomizer won't screw all the way in and won't make contact with the center pin, thus requiring the 510-510 extender.
