The most commercially successful revolvers shooting rimless rounds are the Ruger convertibles. And by commercially successful, I mean have been in continuous production since they were introduced in the late 60s are are still in production today.
I believe this is because they ALSO shoot a popular rimmed round. Its a pretty rare thing for someone to buy a Blackhawk convertible to get a 9mm or .45acp revolver. Though there are some that do. I was, in 1983.
I bought a Ruger Blackhawk 45 convertible with the sole intent of getting a gun that would shoot the same ammo I used in my semi auto, but one that didn't leave me hunting in the weeds for my brass.
That
was the plan. I made one
small mistake...I bought a box of .45 Colt ammo (Winchester) and my "mistake" was shooting it first. The gun roared and the muzzle pointed to the sky. WOW!
From that point on, I was hooked on the .45 Colt and in all these years since, I think that Ruger has only had about 300 rnds of ACP put through it. Years later I went looking for the .357/9mm but there weren't any around locally right then, and I found a great deal on a .357 without the 9mm cylinder, so I bought that, and I've not bothered with the 9mm in revolvers since.
The original S&W and Colt 1917s were built to use HALF MOON clips (3rnd) and speed of loading was not the point. The point was reliable simultaneous EJECTION. The fact that the revolver could be loaded faster was a plus, not the intended purpose.
In the 20s, Western (I think) came out with the .45 Auto Rim, for use in those guns without clips. The "full moon" (6rnd) clips popular today are a fairly recent innovation, relatively speaking, and due to various tolerances, don't work in all guns.
Another gun, not previously mentioned, is the Mk VI Webley. Many of them were "shaved" to allow the use of clipped .45acp brass when supplies of .455 ammo dried up. I have one that was "just barely shaved" apparently a bit less than most others, and it will work fine with S&W half moon clips, but won't work with any others, won't work with any full moon clip I tried, and won't work with .45AR brass. They are just too thick. I also have a handful of 2rnd clips (1/3 moon?) no idea who made them, or when. My Webley does work ok with them, too. Also I am aware that Webleys converted to use ACP brass in clips should NEVER be shot with ACP ammunition. standard .45acp ammo is too hot, use the BRASS not the ammo, and load to Webley pressure levels only.
The thing with revolvers chambered for rimless rounds, particularly 9mm is that while they sell some at first (novelty factor) the demand tapers off rapidly and doesn't justify continuous production. Several models have been made, none of them has been able to last in commercial production.
Other than the Ruger convertibles, where the rimless round cylinder is an accessory, rather than the primary or sole purpose of the gun.
9mm, 10mm, and .45acp DA revolvers have been done, some good ones, but low demand means they get dropped, eventually. Some are in production today, or were until recently. If you want one, get one, but don't expect to always be able to get a new made one.
There were some .25acp revolvers made in Europe, I think before WW I. And often the .32acp will work in some .32 revolvers. This is because those rounds are technically "semi-rimmed" and not true rimless rounds. All of Browning's early case designs, .25, 32, and .38 were semi-rimmed, as at the time he wasn't certain a true rimless round would be reliable. He did change his mind (probably because of the 9mm Luger) and designed the .45acp as a true rimless round.
