....not to be argumentative here, (well, ok, maybe a LITTLE
) whoever said that revolvers don't jam is just wrong. They can, and do jam.. let fouling build up on the cylinder face, or a powder flake get under the ejector star, and you can lock one up in a heartbeat.
But, you are correct, that for the most part, revolvers are pretty simple to operate.
