I have had some time now to run the P07 and Px4 compact side by side on my last few range outings. In fairness, I have had the Px4 since about March and bought the P07 in August and have about 1,850 logged rounds through the Px4 and just over 500 through the P07. Both got some undocumented rounds through them shortly after purchase just to get a feel for them and what they like. So, add a couple hundred to each of those numbers. The Px4 has received stealth levers, a Wilson 12# hammer spring, some stippling, and the Ameriglo sights. The P07 is still box stock.
The targets in the pictures were shot somewhere between 3 and 5 yards and were done about as fast as I could go in a cadence drill before throwing rounds out of the 2" circle.
I still need more range time with the P07. I do not feel that there is enough difference in the shooting characteristics to be of much practical difference between the two. I feel that if I were without one the other would perform as an equal to the other. The P07 trigger is not as refined as the Beretta but I'm not seeing a practical difference as a carry gun in what I can do with it. The curved back of the Px4 slide does make for a bit more comfortable carry though. The Px4 also seems a bit more gentle in recoil and as I track the front sight seems to have less muzzle rise. My wife can operate the slide more easily on the Px4 as well.
I wouldn't discourage anyone from picking up either as a carry option (Yes, I realize 500 or 700 rounds is not a lot for "vetting" the P07 as far as reliability goes, but if it make the 2,000 round mark with the same kind of reliability the Px4 has then it is a pretty good sign. So far it is off to a good start though).
