Short of using the smallest backstrap on the grip I don't think anything can be done about the reach on those guns. CGW offers a short reach kit for the standard 75 series guns but nothing I see for the P-07/09. They do offer a modified 85B trigger for the P-guns which is adjustable for pre travel and over travel so that might move the trigger back some on take up but I'm betting probably not as much as you are looking for.
