Are there any other gas-seal revolvers out there?

I assume there were prototypes and experimentals of the Nagant, but I don't know of any other production revolver with a similar gas seal, or that used special ammunition to complete the seal.

Iver Johnson made an eight-shot .22 revolver called the "Sealed 8" but the "seal" consisted of flanges around the cylinder, front and back, to contain side flash as well as any gas from a burst case head; the cylinder didn't move or fit around the barrel.

Of course if you really stretch the meaning of "revolver", the Puckle gun's cylinder moved forward to close the barrel-cylinder gap.

If you don't mind going back another 35 years, the Savage "Figure 8" revolver had the cylinder moving forward for gas seal. Of course they are not selling thousands of them cheap so they might not qualify as "out there."

Good call on the Savage, Jim.

The Iver Johnson Sealed 8 was made for some time and one should not be very expensive. But as low cost "plinkers", they rarely turn up on the auction sites.

There was also the Knights Armament suppressed GP100.

The Nagant had a civilian vairiant that sold in very small numbers and would be a rare collector's item today.

There was an experimental revolver consisting of a 357 barrel on a 44 revolver, The 357 bullet was in a ring shaped Teflon sabot which stopped at the barrel breech, sealing the gap. An obvious drawback would be the potential for firing a 44 cartridge in it. Not good with a 357 barrel. There would be a potential for bullet jump as the Teflon might not grip the bullet all that tightly.

Just curious, did you ask which revolvers was has sealed so you can makes it suppressed?

I think people make waaay too much of the loss of power between the cylinder and barrel of a revolver. It's overly exaggerated.

I had a 45acp revolver with a 6" barrel and it would deliver higher velocities than a typical 1911 with a 5" barrel with the same ammunition.

I had the opportunity to handle that weapon and ammo. Very exotic, but as I recall, the gas seal was in the round...which was a proprietary load. The can was not integral (quick detach). The caliber was...unusual.

Nice gun for very special purposes.

It does exist. And it is used by certain people in the real world (as opposed to existing only as a prototype).
