I have a High Noon Slide guard OWB, a Garrett OWB and a Tucker IWB on order. Both my PCR and my P01 fit with a little tweaking of the retention screws. So, In my humble opinion, if two out of three fit, I see no reason why the SP01 will not. Also on my High Noon is not formed on a decocker mold but on a compact with a safety and it's gradually taking on the decocker lever indentation. I really like the Garrett due to its minimal size and the fact it can be canted 360 degrees and I am using it as a cross draw/driving holster. In North Carolina we do not have an open carry law either for or against but we do have CCW laws.
