I actually like the PX4 compact, have not yet bought one but one day I will, particularly now that I learnt is quite customizable.
I have read some caustic posts here about rotating barrels, but my experiences shooting a friend's PX4 have been excellent, and I have had a STI GP6 I bought for a song years ago that shoots amazingly well. It's a beautiful CZ clone, with a trigger to die for, incredibly soft to shoot and accurate to a fault.
