I only have one P09 9MM. I have several CZ 75 Compacts, a P01 and a Pre CZ 85, all in 9MM.
While the CZ 75/85 pistols feel very good/comfortable in my hand, none of them shoot, for me, like the P09. It's a laser if I do my part. My first range trip, at 12 yds., off hand, I had to shoot 3 shots to see the hole get a tiny bit bigger in the paper. And yes, the group went downhill during the next 16 rounds, but three rounds tearing a hole I had to walk out to the target to examine (and convince myself it really was a tad bit bigger) is awesome.
If I felt the need for another tack driving 9MM I'd go get another P09.
Oh, I saw mention of suppressor ready P09's. Be sure, if your intent is to eventually get a suppressor, that the pistol has more than just a threaded barrel - you want suppressor height sights, too. Otherwise you'll spending money for those as well as the for the suppressor. I've seen "suppressor ready" pistols with standard sights.
