thanks for all the suggestions so far. It occurs to me that although the .380 is considered "outdated" by many, there are still a lot of even current designs based on that caliber. Didn't hear much about e.g. the .25 NAA or 32. NAA after the first hype...
Does anybody know whether there are newer "handgun specialized" calibers to come on the near future? (apart from the even (nearly) pocket sized 9x19ers that also appeared recently, but that is merely an old major caliber in a small package)
