To answer the OP, no. I do not see any major gun manufacturers introducing any new firearms in either .25 or .32acp.
Technology has rendered them obsolete. Don't confuse that with ineffective because that is certainly not what I mean. Anyone competent with either can certainly defend themselves with said cartridges, but advances in design, especially in .32 caliber(30 super and .327 Federal), have much better potential.
I have a Beretta 950 in .25acp. In fact it was the first centerfire handgun I ever bought, maybe in 2002 or 2003. It is fun to shoot at the range and I probably feed it 50 rounds a year or so. The last time I carried it was probably three years ago and that was just for a day or two when I was in between holsters for my J frame.
Relevant to this thread, I actually pulled it out on a very hot day a couple of weeks ago, loaded it, and got ready to leave the house. But then I went back and got my Ruger LCR in .327 Federal. I would guess that the vast majority of posters that read this would make the same choice. Which is why you won't see any more .25 or .32 acp. There are better choices.
