The Model 632 Pro Series was available in .327 Federal for a short time. When one comes up for sale occasionally, it usually takes around $1500 to buy it. .32 H&R was produced in the 631/632, 431/432 and 331/332. These were, again, produced for only a short time. When you can find one, expect to pay in the vicinity of $1000. As stated, the only other option is the K frame Model 16-4. Expect to pay a minimum of $1000, if you are really lucky.
The only other option for a S&W revolver is to purchase a decent 30-1 or 31-1 chambered in .32 S&W Long. The cylinder in the dash 1 can be reamed to accept .32 H&R. And that's as far as you can go.
If you do not have any objection to carrying around a tank, the Ruger SP-101 can be had in .327. Or if you don't mind carrying ugly, the LCR in .327.
Lastly, if a .32 H&R is on the table, Charter Arms produces a few. I, for one, am tired of waiting for S&W to come out with a decent concealable revolver in .327. Looks like a Ruger is in my future.
Edit to add: I forgot that the Ruger GP100 can be had in .327, if you want an even heavier tank.
