I won't give any advice on what pistol meets your desires, but I will give you something to consider.
If you ever do have to use that pistol for personal defense, you are going to lose it, for a period of time. It will be evidence, taken and kept by the police who care nothing for the treatment of the gun, only its chain of custody.
You won't get it back, until ALL legal proceedings are completed, and you are found to have been entirely in the right. This might be days, or weeks, or months, but COULD be years under certain circumstances.
For me, it makes better sense to use a less than top of the line high dollar combat piece, I prefer a simpler cheaper to replace gun, so long as it uses an adequate caliber and is proven dependable.
Your gun, your wallet, your choice...
