Like I said, I don't know much about revolvers. So, I'll take someone else's word for it. Especially when I look at their past posts.

If a ruger bearcat can be chambered into 327fed i dont see why a nagant couldnt be chambered into 38spcl it will take some serious work and $ but its a possiblility.

Like the Bearcat, you would have to make a cylinder with fewer than seven chambers and best to beef it up to as large diameter as the frame will accomodate. Then retime the action. Install a .38 barrel.
A sharp machinist and a knowledgeable handloader could keep the gas seal feature, make correct length cases out of .357 Maximum like I did for .38-44 S&W Target.

Got pictures and conversion details?
A .22 WMR makes more sense to me than a .327.
I wish the non-gas seal Nagants and other European revolvers were in better (cheap!) supply. I agree with Jan Stevenson that an 1892 French "Lebel" is about as modern as a revolver needs to be.

For a while in Shotgun News there were aftermarket cylinders for the Nagant that were in 7.62x25mm Tokarev.
Then they quickly disappeared, and all that was for sale was 32acp.
I don't think they were new, but reworked surplus, but I am not sure from the pic.
If the chambers are now .361" in the rear, and they had to be opened up to .387" for the Tokarev, the the metal between chambers would have gone down from .060" thick to .044" thick.
I run 22kpsi in a 45Colt with .041" between the chambers.
Hoop stress in proportional to inside diameter, so .480" chambers are worse than .387" chambers by ~ 25%, so maybe 30 kpsi might be ok, but the Tokarev ammo not from Russia all measures 42 k c.u.p.
So I would not have done the Tokarev conversion, for that reason, and another is that I see the Nagant pistol as a piece of junk. I will spend my time working on Colt Single Action Army revolvers that pre date the Nagant and are superior.

Just because you can doesn't mean you should. Many ill advised conversions have been done over the years. The most common is the rechambering of S&W M&P Victory Models(pre- model 10) revos from the British 38/200 to 38 Special. It worked, but produced a very sloppy chamber with poor performance and near zero case life for the reloader. Ruined a semi-collectible gun in the process.
A wise gun owner/gunsmith will know the pertinant facts before beginning such a project. Chamber wall thickness, frame cross sectional area, barrel/frame thread dimensions, metallurgy, pressure curves, peak pressures, .... all play a part in determining whether the project is viable/safe. If you or your gunsmith cannot answer those questions accurately, you don't need to be doing this.

@Jim Watson- Sorry, no pics on file and the piece is in long-term storage so I can't shoot any right now.
The conversion was pretty simple to 22LR, if a bit nitpicky. The Russians hogged out the firing pin tunnel in the frame & just bent the original firing pin up to make it rimfire. I made a whole new firing pin and cut a slot in the frame to clear it. Needed a slot in the breech block (vs. the firing pin hole) as well. Far as I know the Russian conversion used inserts that let the cartridges sit flush with the insert rear face. I left them protruding, so I had to grind a bit on the breech block face for clearance, and the breech block tunnel got a radiused edge on the right side to keep the cartridges from jamming if they slid back in the chambers. Hardest part was making the inserts because the Nagant round is a slightly tapered case, LOTS of hand fitting required for a tight fit. Swapped out the barrel for a section of Marlin micro-groove barrel from a rifle project, contoured it like the original to maintain the gas seal feature and use of stock ejector.
A long project, but worthy. It shoots great.

The Negant has a cyl. that moves forward to seal the chamber to beral gap , this would make things verry dificalt
