Not an essential component. I imagine you could make your own detent if you really wanted to. But you'd have to find a very small spring somewhere, you might even be able to wind your own. I was never sure just why S&W ever used them. I don't think Colt ever did, at least I've never seen a Colt with a crane spring and detent.
The cyl hold open detent is an old world touch. It's an early feature to keep the cyl open when loading/unloading to prevent it from slamming closed if the gun is tipped to the right slightly, and scratch the recoil shield with the extractor star.
Plunger shown here in bottom of yoke and has a spring underneath it:
No you don't have to have it, but it's handy. The best thing is, it's so simple to make.
First thing is to check the hole with a dental pick, the spring may still be in there.
TO MAKE the detent parts: (Posts 67 -69 in link below). Just get a drill bit close to the hole size, cut of the shank to size below, and just round the two ends a bit with fine sand paper to remove any burrs and polish both ends.
N frame plungers are in the .540" to .570" length range. The yoke detent pins measure .100" to .101".
A BIC lighter spring works perfectly.

When the yoke is pulled from the frame, use care or the plunger and spring can be launched across the room never to be seen again. Often because of this, the parts are missing. But check the hole in the yoke for stuck or rusted parts.
It's quite simple to add this feature to any hand ejector that wasn't made for one. The yoke shaft is hardened somewhat so plan on using a cobalt or carbide bit to drill the hole.

It wouldn't be correct, but the spring behind the "flint" in a Bic lighter would most probably fit. There are a couple of springs in the Bic, and years ago when I still smoked I would smash them up when they ran dry and remove the springs. I can vouch they will work behind the 4th screw in the trigger guard of a K or N frame.
