At face value, that would be a hard choice for me. But, you said you don't gee-haw well with your PCR. That changes things. I don't know why an idiot like me had such an amount of money in my pocket at one time, but I bought a VP9 and a CZ P10C at the same time or there abouts. Man, I really dig both pistols, but I shoot the P10 just a tad better. I also have a PCR-D that I like and shoot really well, but since I got spoiled on the polymer lightness, it stays home now. If I didn't do well with the PCR-D, I think I'd let it go if money wouldn't let me have both. Having rambled all around here, I guess I'd have to say Go For The H&K.
Just a thought... about how many rounds do you have through your PCR? The reason I ask is that I either shot mine low, or it shot low until probably 300-400 rounds. It doesn't seem much, but it was shooting around 6" low at 25yds and over time, it eventually came up. It could have been me, but it seems like it was a matter of having a break-in period.
