Unique revolver made in Spain, 3 barrels, 18 shots, 3 firing pins, 6.35mm pistol cartridge (Via)
Unique literally means “only one.”
I think the potential buyers for this presumably prototype thing may have realised all the ways it could go wrong and decided “maybe not for me…”
(After all, if it was such a good idea, why aren’t there more of them…?)
That thing must kick like a freaking mule. They probably decided not to mass produce when the first test fire resulted in a Tom and Jerry-esque tooth-crumbling scene. Not to mention that simultaneously firing three rounds probably really screws with the ballistics. I imagine it gives a shotgun-like spread. When dealing with a short-range weapon, having all three projectiles go askew means you’re probably gonna die.
