I can see the .380 being marketed overseas. Here in the US, if you want locked breech in a .380 pocket pistol -- look no further than the very reasonable KT P-3AT. Mine has been reliable out of the box, and was my daily pocket carry since it replaced the P-32.
I've come to feel that the smaller (less powerful) cartridges are not sufficient to be considered effective as a self defense pistol. (I know, better to have something than not).
The R9s (or other 9mm) to me, is the minimum for self defense. I now prefer something stronger -- .40 or .45
Thr R-380 will sell, and I expect it will be the Cadillac of pocket .380s -- but if the price is expected to be in the same $900-1000 range, I'll not be adding one to my collection. Too many suitable, lighter, and less expensive .380s on the market.
