I have an 85 Combat and a PCR. The 85 is my favorite target 9mm and I like the PCR for carry, chose it over the PO1 because of the slimmer slide.
Neither pistol has had any trigger work done on them, after several 1000 rounds they have smoothed out nicely and I've gotten use to them.
Only complaint I have is with the serrated trigger on the PCR, it's hard on the finger after a couple hundred rounds. Don't know if the PO1 shares that feature.
Both pistols are extremely accurate with the edge going to the combat with it's longer sight radius and extra weight.
The 85 Combat has been discontinued.
I love the 85 Combat too. IMO, if more people knew about the 85 Combat, it would have outsold the 75B back when it was in production. I have made gradual changes to mine, currently has the following parts that elevate the gun to an amazing level, nicer trigger and action than the factory target/competition guns I've handled, but of course it doesn't have the additional heft of the larger target/competition guns.
CGW 54460 Ultra-Lite Kit using the range hammer spring (provides a noticeable improvement in DA and also SA trigger pull, and makes it easier to rack the slide (not that CZ have hard-to-rack slides, but the kit will make it quite a bit lighter)
CZ Pre-B short trigger reset (does what it says, shortens the trigger reset -- this is a CZ factory part)
CGW 6-SAO trigger (with adjustable uptake and over-travel)
CGW Race Hammer Kit (improves trigger pull and essentially eliminates the characteristic CZ hammer "camming-back" in S/A.)
CGW floating trigger pin (just a simple item you need with the SAO trigger)
With the above setup the trigger is very nice and light, crisp, and operates fore and aft within the range of the thickness of the trigger at the mid-point.
I, too, find the PCR trigger to be a little rough on the finger if shooting quite a bit in a single outing. I keep meaning to install the factory 85 Combat trigger in it, but just haven't done so. The P-01 has the smooth trigger like the other 75-based guns.
