You can find glowing range reports from someone who has fired a couple of hundred rounds on their new pistol all day long. This is not one of those. I purchased my P-07 new in 2012 (B serial version). I wanted to try one, but the main reason is we had our neighbors 12yo daughter get interested in doing defensive pistol competitions with us (her mom came along to watch). I started her using our Walther P-22, but after just one match she wanted a 9mm, which I was out of (my 12yo was using my 75B, my 14yo was using his XDm 5.25). So I got the P-07 to fill a hole, and I was curious. The pistol was primarily used for practice and shooting defensive pistol courses by the girl. Sadly, by the next year they moved away. My young son took a shine to it, so it was used in IDPA, USPSA, and 3 Gun. We also shared use in some night matches as I could attach the light. All this shooting was done using 124gr cast lead bullets, which translates to very dirty ammo. The shooting environments typically are very dusty, with some sand in there. Right now the pistol is just over 5000 rounds. Pros: The out of the box trigger (Omega) was excellent, quite a bit better than a stock 75B. I found it easy to shoot, and so did all the kids. CZ Service is fantastic Your 75B magazines will work Cons: Typical for polymer pistols, it did not like limp wristing. It would load the round, but would fail to fire. When the magazine well gets dirty, like really dirty, the magazines will stick. Don't load 16 rounds in the 16 round magazine. If you have large hands, you may find the grip too narrow. I fixed that by adding a rubber wrap around grip when I use it. I did send it back due to the sticky magazines. Turns out I had early version (blued), and they replaced all 5 of mine with the new version. Mine were also sticking due to a burred edge that developed due to all those mag loads, which I now keep an eye on and take out with some sandpaper. Despite the extra maintenance, I still like this pistol. I shoot enough to know that all of them will have issues, it is just learning what they are and then how to fix them. The kids have moved on to other pistols, so I have it around as a home defense piece with the light attached.
