My wife carries the Walther PK380 and I really enjoy shooting it. I had the old S&W Sigma 380 (look it up...it's a 90s era firearm) but that was a piece of....well, you know. I really like that PK380 though, yes you can get a 9mm in that size or smaller....so what. I carry a LC9, but my wife is more recoil sensitive than I am and I would rather her have 9 rounds of 380ACP that she is accurate with than 8 rounds of 9mm that she isn't (and doesn't like to shoot). Let's face it, a LC9 (and very small light 9mms like it) are not the most fun firearms to shoot. For all of you "380 BLEH...9mm is as low as it goes" folks, that is why someone would choose a 380ACP over a 9mm Luger that is the same size package...recoil sensitivity (which leads to inaccuracy, not practicing and not liking the firearm you are carrying and eventually not carrying).
I also really, really like the Beretta 85, for which I am currently in the market.
Frankly, a kel-tec p3at. I've bought two, traded one of them, and have been pleased with the overall performance of them. I wish there was a little more quality in the finish and design of the gun, but I didn't buy them for their looks.
I absolutely love the Kahr P380. Great quality and reliability. I almost bought the Glock but the size of the Kahr helped me with my decision. It is a true pocket gun. Very accurate for its size
JMO, but since there are a multitude of small 9mm's (and even a few .45's) as small as .380's, carrying one just doesn't make sense for me, not even as a BUG.
Glock 42. I love shooting it. I've been extremely accurate with it, and with Talon grips and the pinky extension, it feels great. Inside a Flashbang Capone IWB holster, I don't even know it is there, all day long. I've gone from light clothing summer carry with it to carrying it even in the winter. I just picked up a Glock 43, which is slightly larger and slightly heavier, so we'll see if it will unseat the 42. I'm not yet convinced it will.
Btw, with the right ammo, the .380 can consistently meet the FBI standard for penetration. Also, it WILL go right through a windshield and hit the target, even from an angle. But what is the likelihood of that kind of scenario? I think it is less than slim.
