I don't know yet if this is going to be normal for this pistol, but it seems to shoot Rem UMC ammo to the same aim point and with good accuracy compared to my standard (and expensive) Atlanta Arms 115 JHP. I don't recall having this good of a result in the other CZ's, but had good results with UMC in my Sig pistols. Video from Friday morning ...
https://youtu.be/fFSJNkfHCsAI shot targets out to 50 yards with results about as good as I would have expected from the "good" ammo, but returned to the steel targets instead of shooting a rigorous bullseye practice session with the UMC. I may do some more testing this coming week. And stock up on the UMC buckets at Academy when I get home.
