I do own 2 guns in .327 Federal and yes, finding them can be tough.
The good news is that Ruger is releasing the Ruger GP100 and the Blackhawk into the pipeline as this is discussed. It'll take a while before they let things loose completely. Both of these models are in...... .327 Federal.

I have the Taurus snub in .327 and the Ruger SP101.
I've fired the Federal ammos through them and they are a handful, but doable IMHO.
The great thing about the .32 calibers is that the ammo can be tailored to the mission.
Since .327 Federal ammo is expensive the .32 S&W Long and the .32 H&R magnum ammo can be used for practice, fun, plinking,or for the recoil sensitive or the infirm, as a defense round. Yes,I know there are better choices for defense. The .327 is one of those.
However for us who are getting older, have RA or other arthritis, or some other malady, the .32s offer a better choice.
No slides to rack, simple manual of arms, better than decent reliability, and other reasons to go with a revolver over a pistol.
Want to introduce someone new to firearms? The .32s do it in a way that the larger calibers can have trouble with. Low recoil and muzzle blast from the low powered .32s make that a breeze.
Granted, the ammo can be hard to find in some places, but after some judicious searching I have found many suppliers so I do not run out or have to wait long for ammo.
Some say that the .32 ammo is high priced. Depends on where you buy it from. I can say that I find the .32 S&W Long and .32 H&R ammo is either slightly below or at what .38 Special ammo is running at.
That or reloading can be done. Why not?
The .327 Federal ballistics are nothing to sneeze at.
In recent years there are outdoor adventurer gun writers who expound the 32 calibers as carry guns in areas where bears are not a likely problem to need a larger caliber for.
Most places I hike and camp there are bears, but they stay away or are met very infrequently.
All depends on your needs and situation on a case by case basis.
Finding the .327 Speer 115gr. Gold Dot is a large problem.
Oh,well. I'll just keep looking.
