Only a rumor, probably came from speculation about whether they would make one now that NAA is making a Guardian .380.
Kel-Tec produces (or used to produce?) a .380 for sales overseas but that is in a P-11 size pistol, not a P-32 size.
If they ever tried to make a .380 in a P-32 size pistol, they would probably have to make it bigger as NAA did.
