Adding a comp to a 75 or SP01?

[MikeG22]

I have a SP01 (9mm) that I'd like to add a comp to. The CMORE serendipity is going on soon but i'm unsure of comp options on this thing. Anyone done it or seen it?

The stumbling block seems to be the extended barrel. Any good smith can make a comp.

I have wondered if you could chop the slide, then use the factory barrel and thread it for a cone comp? This is getting pricey fast...
