What safety do you need? The safety feature of the Kel-Tec P32 is the long, firm pull needed to fire the gun. This is the same feature that protected hundreds of thousands of cops who were carrying revolvers (which also don't have manual safeties) without incident. I was among them. Many cops (and countless civilians!) continue to carry service weapons that do not have manual safety levers or devices. These guns will not fire unless the trigger is firmly depressed rearward.
My current every-day-carry (EDC) piece is the Kel-Tec PF9, which is simply a "big" P32 chambered in 9mm Luger. It has no manual safety. I also do carry the P32, when I can't carry the nine, which is generally while traveling to and from my current profession's work site.
Do you live in an environment in which the safety "between your ears" is not enough, such as where one is required (or you have a spouse/SO who demands one)?
If so, there are options in .32ACP from Beretta and Bersa that offer a manual safety, but they'll be larger than the Kel-Tec. With the exception of the Beretta and Taurus "pocket" .22 and .25 caliber pistols, few that small have both a double-action trigger and a manual safety.
Edit: I just checked your history and see that you are learning with a 1911-based single-action semi-auto pistol which is, of course, equipped with a manual safety. The Kel-Tec's trigger requires more effort and travel than your .380. If you personally can safely carry a "cocked-and-locked" pistol such as the one you're getting used to, you'd have no problem implementing a safety-aware mindset to carrying a double-action handgun with the hammer at rest and the safety off (or with no safety at all.)
