I own an HK USP 9mm.

It fits all your requirements except #5. The reason I chose the 9mm version was because it is great for rec shooting and the ammo is a lot cheaper than .40 and .45. I am pretty sure you know there are the compact variants of the USP, so you can get one that fits all 5 requirements!

The only drawback some people dont like about the USP is the polymer grip. I find it to be great however because it greatly dimishes the overall weight and makes it less taxing to shoot.

As for home defense, I honestly think anyone breaking into your house wearing body armor is someone really willing to take you out. Even with higher caliber handguns, you probably won't stand a chance being half asleep anyways. So for all those other people who won't be prepared, 9mm at < 7 feet would probably be good enough to drop them.
