Andy;
I decided to go with the P07 and managed to wring it out with just over 100 rounds. I chose the P07 over the Beretta PX4 based on natural pointability (for me) and a preference for its profile in my hand. I'm real happy with the gun so far; not one malfunction, and accuraccy was excellent at five (one handed) to forty-five feet. I made a point to shoot DA first shot in order to get a feel for the transition and I was pleasantly surprised at the shot placement consistency. It has a pretty heavy DA pull and it's creaky but I could feel it smoothing out a bit even during my limited session. Decent enough that, with more practice, I won't notice it. SA is easy but not silky-not enough to throw you off, though.
Just as a comparison, I have a Walther P99 in 9mm that's been 100% reliable up to 3000 rounds but its ergonomics were just a shade off for comfort, in my hands. That's even with changeable backstraps. The P07 was very comfortable right off, and I felt like I could shoot it all day minus any annoyance. I have only felt that way about .45 ACP through my Glock.
For carry, the P07 is balanced well and comes up on target very quickly. It's not quite as natural a pointer as the CZ Phantom, at least in my hands YET, but, hey, I've only had the P07 a day and it's way more comfortable to shoot a lot than the P99. (The point is, the P07 is comfortable enough and fun enough that I'll be shooting quite a bit through it). Muzzle flip is definitely there but easily controlled with firm wrists and the weapon pops right back down on target as if on rails.
Good gun, so far and I don't regret my choice at all. I'll check back with you after 3000 rounds. Hope it helps.
