If you can miles try one of the necks with the B width nut, you might be pleasantly surprised, my 71 precision and all the early ones I’ve had have ( like most from 67/68) a 40mm nut but they are very comfortable , I’ve played mainly jazzes for years and I can pick up my P and not really notice a difference , the mid to late 70s ones can come up a bit chunkier, but not the earlier ones
