From The Truth About Guns:

When I heard about the Naroh N1, I wasn’t expecting it to be as small as it was. Note the photo above. That’s my GLOCK 42 in .380 ACP on top of the Naroh N1 9X19. I swapped my G43 with the G42 because the G43 was just a little too big to boot carry.  I can boot-carry the N1.

Although the N1 is Naroh’s first 100% in-house-designed firearm, the same folks have been wholesale suppliers for other people’s gun parts for years now. They already have the machine capability, the in-house design team, and several patents.
