Says the RDO is only for the P30. Given how similar the USP Compact and P2000 are otherwise, I assume there's something that prevents the install for the USPC/p2000?
edit: or maybe not?

It's still early, that could just be an error in the ad copy but it sounds like the USPC is fair game.The HK USP 9 and 45 pistols haven’t received much extra love or attention. In partnerning with Lipsey's to bring love to the USP 9 and 45 models, we now have the LTT HK USP 45 Full-Size with the LTT Trigger Job and low RDO Cut, exclusively through Lipsey’s. The full pistols can be ordered by your FFL dealer through Lipsey's. Already have a full-size or compact USP 9 or 45, no problem, we can upgrade it with LTT's secret sauce.
