I don't think this is 9mm. Waiting on the seller to get me info on if a round will fit in the chamber.

Anyone seen one like this before?

Looks like a 380 FA to me. And a sketchy one.

Isn't 380 a 9x17mm?

It appears to be a semi open bolt carbine upper.
RPB made semi open bolt pistols, M10’s and M11’s and they also made Semi open bolt carbines.
