What's the smallest 9mm that you really enjoy shooting?

I'm shopping for my first gun(s). I will almost definitely be getting a Bodyguard 2.0 because I've always been super picky about minimizing my EDC setup. But I also see myself wanting a more capable gun on me some of the time. I figure if I'm getting something bigger than the Bodyguard, it should be nice to shoot but still as compact as possible. So, what's the smallest 9 that you love to shoot?

Feel free to convince me to try a larger caliber as well, as long as it's not a huge trade-off in size.

Edit: forgot to mention I'm in MA so 10rd limit. If that affects your recommendation.
