Universal race holster

[GMP]

So I have a CZP09 I did a lot of work on I occasionally run in local knockdown matches that can be started in low ready position.  I'd like to try this gun in Steel Challenge and possibly USPSA but do not want to buy a dedicated holster as I plan on a new TS2O in the near future.   The P09 has a Toni frame weight, Holosun 507C, and Primary Machine comp(small 2 port). Does anyone know what holster may work, with adjustments of course, for both guns?  Thanks.
