disposable firing pin

right off the bat here, i'm not trying to prove or even discuss the effectiveness, humanity, or anything otherwise political about firearms. this is simply an idea about possibly improving the performance of the revolver.

revolvers have few moving parts but lack a single-action trigger pull, because you have to cock the hammer back either with the double-action trigger or manually with your thumb. semi-auto pistols solve this problem with a complicated recoil or gas dependant system. the problem is all these extra moving parts in the gun leave it slightly more vulnerable to jams, etc.. although for civilian home defenders or concealed carriers the difference is probably negligible, for police and military a new solution might be welcome.

i propose a small package about the size of a couple of tums (depending on the caliber of the ammo in question) that contains a pre-pressured spring and a small firing pin.

this is either put in the full-moon clip of a revolver, or factory-mated to the cartridge itself. the revolver, of course, would have to be a new model, with no hammer of its own. the trigger-pull would merely push a small pin into a needle-sized (or smaller) hole in the package, which releases the spring inside, driving the minature firing pin against the percussion cap, thereby igniting the fulminate, and the rest of the firing of the cartridge goes normally as before. trigger pull would probably have to turn the wheel, thus the pull wouldn't be a true single-action pull, but at least significantly reduced.

alternatives might include the same deal but with it statically and unremovably integrated into the wheel of the revolver. (a reloading scenario would have the user cock each of the six {in a six-shooter} packages, by some mechanical means {either one at a time or all at once} or these springs could be factory-wound and disposable. (probably not cost-effective that way)

could also scrap the whole idea and think about achieving the same ends with a solonoid-type ignition system. this would require a battery, though, which would have a shelf life, and might run out at the peril of the user during an emergency.

problems: a spring so small be even possible with enough force to set off a round? if this is hard to do cheaply, it might be possible to use a new primer mixture that is more sensitive and would need less pressure. (perhaps with partial amounts of silver fulminate) Although, of course, a less stable primer might be less safe.

i might be missing the whole point here too. revolvers are supposed to be drag-through-the-mud reliable. making the cartridge (or a mate for the cartridge) more complicated might ultimately prove to be unreliable in itself.
