Reference my holster search for the P365XL:
I contacted Mitch Rosen, up on New Hampshire, who make the Upper Limit, which I liked very much for my G26 and G19. MR indicated they only offer the UPL and UPL-EXP for the shorter Sig P365, but they do make the the 5JR and 5JR-EXP for the Sig P365XL because it accommodates the RomeoZero laser. They said they would continue to evaluate the market and let me know if they ended up making an UPL for the XL.
Also, I got a very nice response from the Raven Concealment Customer Services representative, who indicated that their design team are working on a P365 Perun, and should be "released within the next two months."
