I have a p365x which I purchased a faxon threaded barrel and compensator.   I’ve been running a PMM comp on my other pistol and I got a deal on the faxon.   It turns out the faxon is 10mm longer.   I can’t fit it a macro holster (w/ frame) or any other holster I have that
My PMM set up works I.   Any suggestions?

I ended up taking a heat gun to an existing holster and opening up the bottom a touch.   Worked like a charm.
