The only reliable .32 I can think of offhand is the Kel-Tec, but these will sometimes need the feedramp polished and the frame/slide mating surfaces smoothed out a bit in order to run 100%. If you don't mind taking the ten or fifteen minutes to do this, you can have a very reliable backup. There are a few others such as the Seecamp and the Beretta Tomcat, but these can at times be very problematic. The Taurus Millenium and the NAA version iare supposed to be decent, but I've not used one of these.
I have to wonder why you would pick the .32 for these purposes. They don't make good plinkers as they are expensive to feed and will not be very accurate. Some can be found in .380 in the same sized pistol, and .380 is cheaper to shoot and more powerful to boot. Also, some .32's can experience rimlock (it's a semi-rimmed cartridge), which will not happen with a .380. Anyway, not to criticize your choice, but just wanted to post food for thought.
