I know they can be hard to find sometimes. I found online that Davisons, the Dist in AZ, is exclusive with Bersa for the Duo-tone Thunder 380 Plus model. They show 99+ in stock in case any one is looking for one. I contacted my dealer and ordered one for myself this morning, and other than my love of that model Bersa, have no connection with that Dist.
