I think the Seecamp .32 is possibly still in production and/or the North American Arms (NAA) Guardian in .32 ACP. I think there still might be a Walther PPK in .32 ACP still in production, too. I had the NAA Guardian once, and it was only so-so for as expensive as it was: VERY heavy (all stainless) and kinda thick, field strip button was kind of tricky, would jam on the last round BY DESIGN (no ejector), and the trigger was pretty heavy. The Seecamp is basically the same thing, just smaller. Also, supposedly any revolver chambered in .327 Magnum can chamber and fire .32 ACP as well, so it makes for a cheap and possibly lower-cost practice/plinkin' round for those guns.
Beretta Tomcat and Kel-Tec P32 are the only two I can think of that are for sure still in production. Taurus made a PT732 for awhile that was pretty nice, and I probably should've picked one up while they were being made, but now they're outta production and super scarce. CZ also made a 15-round .32 ACP version of the CZ83, as I recall, but I don't think I've ever seen one around anywhere.
I like .32 ACP as a cartridge because, at least in most applications, it's pretty easy to shoot. But I can see that it's not really popular, especially these days, because it's not very big and the semi-rimmed design can present some rim-lock issues with some designs. It used to be really popular in the early 1900's and over time, with the takeover of 9mm as the world's favorite caliber of choice, it's diminished a lot. Still seems to be hanging on in some European countries and other places where civilians can't own stuff in 9mm or larger.
