Kinda hard to say actually. But I am fairly sure adjusting the travel on a compact is not something that can be done out side a gunsmiths shop, or someone very much like a gunsmith. But just to be clear, and no offense intended I assure you, but is yours just a CZ Compact in 9mm or is the CZ 75 D PCR? If it's the second then if Definitely has to go to a real gunsmith because of the way the Decocker interacts with the trigger. If it's is the Compact D PCR, I would think hard about sending it to CZCustom to have them do the trigger work, If as you posted it's the compact then a good gunsmith can do a trigger job on it for you.
