With the "Plus" the thumbbreak will not snap on my holster that is custom fitted for the Bersa Thunder .380....I asked the same question. If you study the specs of both the 380 and 380 Plus, the barrel length is the same, the slide width is the same, and the height is the same. The only thing different is the grip width is .05 (five onehundredths) larger on the Plus. Most holsters wouldn't have an issue with the grip being a little wider. Seems to me.
