What you want is a Dardick.  Dardick's guns were not successful
commercially, but they were basically revolvers with a 3-chambered
cylinder.  The chambers were triagular, not round, in cross-section, and
the outside of the chamber was open.
The rounds -- Dardick called them "Trounds" -- were also triangular in
cross-section.  In the final designs, they were standard .38 or .357
rounds inserted into an aluminium or nylon extrusion.
The Trounds were loaded into a magazine -- actually two magazines, one
on the left half of the grip, the other on the right.  As the cylinder
turned, a Tround would feed up through the open side of the chamber.
In firing position, the topstrap of the gun served as the third side
of the triangular chamber.
One thing about the Dardick was that when the right side magazine was
empty, the gun fed from the left (both magazines together held about 20
rounds).  You could load an empty magazine from a stripper WHILE
continuing to fire the gun.
