Sounds interesting, but risky in chambering an unusual design (underbarrel revolver) with an even more unusual round. But using the .327 Magnum, a much lighter underbarrel revolver can be made for conceal carry or a secondary backup firearm.

The .327 Federal Magnum is a cartridge intended to provide the power of a .357 Magnum in six shot, compact revolvers, whose cylinders would otherwise only hold 5 rounds.

In the April 2008 issue of the NRA's American Rifleman magazine, Field Editor Bryce Towsley summed up his review of the cartridge as follows: "The .327 offers more 'real-world' energy than the .357 Mag., (at least in my test), better penetration and one more shot per gun load. It does all this with substantially less recoil and noticeably less muzzle blast than the .357 Mag."
The cartridge ultimately won the NRA Publications's prestigious Golden Bullseye Award for "Ammo of the Year" (2009). https://en.wikipedia.org/wiki/.327_Federal_Magnum

The .327 Federal Magnum (left) is essentially a lengthened .32 H&R Magnum (right) but loaded to significantly greater pressures. https://loaddata.com/Article/LoadDevelopment/Handloading-the-327-Federal-Magnum/108

Here's a Ruger Single 6 (Single-Seven?) in .327 Federal Magnum & .32 H&R Magnum 7-shot.
I recently bought a similar Ruger New Vaquero 6-shot in .45 ACP and it's a fun bird's head compact single-action.

Because .327 Federal didn't take off as a popular cartridge. Also, going to a low barrel adds mass and bulk to the revolver, since you need the top of the gun profile to stay the same for the front sight. Look at the Chiappa Rhino. Even their 2" barrel versions are bulky as hell.

Called it!
The Rhino's blocky frame is CNC machined from a solid block of high tensile aluminum, but she is still lightweight, although at 24 ounces not as featherweight as some titanium alloy snub-nosed revolvers like the Smith & Wesson Model 340 PD that uses a scandium alloy frame and titanium alloy cylinder and only weighing 11.8 ounces. The Ruger LCRX 5-shot .38 weighs 13.5 ounces.

The Ruger LCR in .327 has a Hogue Tamer grip and a monolithic aluminum alloy frame combined with glass-filled polymer with what Ruger calls a “Synergistic Hard Coat,” which feels a lot like anodized aluminum. Only the barrel and fluted cylinder are stainless steel. And, at 17 ounces, it’s truly a wisp of a handgun.

Waaaaait wait wait.
MORE powerful than .357 magnum? Now I'd assume .327 federal magnum is more powerful than .38 special without thinking about it very long, but more powerful than .357 magnum? No way, that can't be right.

I'd be more interested in a 44 Magnum or even a .454 Rhino. People choose big bore revolvers for protection against dangerous game and faster follow-up shots there could mean the difference between life and death and they wouldn't mind the weight.

A favorite .44 Magnum revolver is the Ruger New Model Super Blackhawk single-action. They are available in 3.75" barrels to 10.50" with very beefy frames. I have a 5.5" and she is a nice 6-shooter. Far more handy than my massive Ruger Super Redhawk scoped 9.5" .44 Magnum double-action.

> So WHY THE FUCK has NO gun company (or at least some nerd with a CNC machine) combined these two technologies to create an under-barrel .327 federal magnum revolver?

Because revolvers are obsolete. I shot a small revolver in .327 and it was alright. .38 snubbys are pretty unpleasant. And .357 snubbys...

> Have you had the chance to fire off one of these ultra-air-light-feather weight pocket revolvers? Using a full house .357 Magnum load? If you haven’t, do this; put your Concealed Carry Magazine down, stand up, walk outside to your car or truck and open the hood… and then slam it down on your firing hand. Quite unpleasant.

The Chiappa Rhino does a pretty good job in .38 but is a bit harsh in .357. If I need a gun to specifically shoot from a jacket pocket, a 2" rhino would do the job. If I needed a compact gun for defense, I'd go for a Glock 43, 43x, or Sig P365 any day, because they can actually be reloaded in a reasonable amount of time.

I found the 2" Rhino .357 surprisingly mild to fire with very little muzzle flip. Well, compared to my double-barrel .410 shotgun Derringer or other .38 lightweight snub-noses.
