I wasn’t sure if you were specifically asking about an SP01 phantom or the regular SP01 or both? But for my carry SP01 I run a TLR-9. I really like the thinner profile of the light for carry, holster fitment, and front load batteries (a minor convenience). the TLR-9 does compromise on total candela when compared to the latest TLR-1 HLs or modlite PL350 but I find it adequate for a carry/HD gun in my use cases.
I have posted pics of my carry SP01 previously:

No personal experience with lasers on pistols but from what I have gleaned from my research is that they don’t hold zero particularly well and that a red dot is much better investment for an electronic sighting system.
