Aww! This is the cutest! Weirdly, I’m using that term for an armament. The SwissMiniGun, measuring 5.5 cm, claims to be the smallest pistol ever manufactured. Apparently, the pistol is so tiny that it requires specialty 2.34mm caliber bullets to be custom-produced. With that size, they’d know that the owner would have trouble finding a holster, so they included one. The gun is not permitted in the US but can be imported in Canada. It can make a good miniature collection item for a retired army officer.
