Two Genius Designs, Yet An Answer To A Non Problem!

The Dardick Pistol.  It uses a three sided round (tround) and the cylinder rotates the cartridge into the open top chamber.  (The bullet itself is normal, the cartridge three sided or a standard .38 held in a triangular plastic sleeve.  Both varieties were used).  Few moving parts, cheap, very reliable. This is the only magazine revolver that I know about. Not  needed at all for a world that is invested in standard firearms.  This is one of the cleverest mechanical solutions ever come up with.  Super rare.  A developing country should consider this sort of thing for their nascent firearms industry.  Works with pistol, carbine and rifle applications.  Could be used in an auto configuration should the necessity arise.  Matched in ingenuity by it's contemporary,

Gyrojet.  This is a sheet metal rocket launcher, cheap, smart, effective, but just not worth the trouble.  A few were used in Vietnam, but they did not perform well enough to be standard issue.  The butt holds a magazine of rockets which are fired by a hammer that hits the front of the cartridge, knocking it back onto a fixed firing pin.  The round overruns the hammer, cocking it as the next round is pushed into place from the spring-loaded magazine. It seems that the propellant cannot be developed to a state that rivals standard bullets. Two or three moving parts.   Again, this would be an excellent choice for a developing, or desperate, nation.  It is reported that firing one of these at night is an awesome experience. There seems to be an attempt to improve it, aka the Deathwind project.  Both these weapons are from the late fifties.
