I've been carrying a Ketec P3-AT in .380 since they came out in the early 2000's. Very concealable as I wear shorts and a T-shirt 95% of the time, but the new S&W 2.0 bodyguard in .380 is getting my attention as it has a higher round count with a frame that is not much bigger than the Keltec.
Currently just trying to find one to stick in the pocket and see how it feels before ditching the Keltec.
