Frequently Asked Questions

How does the Nagant 1895 achieve its gas seal?

The Nagant 1895 achieves its gas seal as the trigger is pulled, causing the cylinder to index forward and seal its mouth against the rear of the barrel. A breech block then pivots into place to support the cartridge case.

What is the function of the 'hand' component in the Nagant 1895?

The 'hand' component in the Nagant 1895 is responsible for driving the cylinder forward into its sealed position against the barrel. This action is crucial for the revolver's unique gas-sealing capability.

What supports the cartridge case during firing in the Nagant 1895?

During firing, a pivoting breech block moves into place at the back of the cylinder to support the cartridge case. This is controlled by a vertical locking block within the firearm's frame.
