I think the myth that a revolver is more reliable than a semi-automated is because a dirty semi-auto is more prone to failure than a dirty revolver. Also, revolvers are more forgiving when the ammo is marginal in quality. I have six semi-automatics and I trust myself to disassemble and reassemble them (I don't get into the triggers) but I don't get into my five revolvers other than changing the cylinders and cleaning what I can reach. I'm afraid of messing with revolvers and messing up the timing. I think a typical semi-automatic is simpler than a typical double action revolver.Arguably the most oft repeated myth of revolver aficionados is that their holy grail of handguns, the revolver, is more reliable than a semi. A good quality semi will whip a good quality revolver in reliability testing. A semi is of simplistic design with few moving parts. A double-action revolver is of complex design with many moving parts, all of which have to work perfectly for a revolver to function as intended.
