Nagant M1895 'Gas Seal' Revolver


Nagant M1895 'Gas Seal' Revolver

The Nagant M1895 revolver was designed and produced by Leon Nagant, a Belgian industrialists. While Nagant designed similar revolvers for several countries, this model for Tsarist Russia is unique as it has a gas seal.

The M1895 fires the 7.62*38R cartridge, unique also as it incorporates the bullet entirely within the cartridge case. The case is then crimped over the bullet leaving a small bottle neck on the end. When the trigger is pulled, or the hammer cocked, the 7 shot cylinder revolves, and then moves forward to insert the bottle neck into the chamber. When fired, the bullet moves forward, pushing out the crimp and forcing it to seal against the walls of the chamber. This prevents the loss of pressure caused by the gas escaping through the cylinder gap like in all other revolver designs, and gives a bit more speed to the round (about 100fps). Because the bullet does not have to jump the gap, it also increases accuracy as it more perfectly engages the rifling within the barrel.



The Nagant M1895 revolver in my collection was manufactured in 1938 and is in very good condition. Because the cylinder must be pulled forward, the trigger pull on this model revolver is very hard, about 20 pounds in double action, 13 pounds in single action (cocked first and then fired).

Accuracy is affected by the hard pull as the strain on your finger causes the gun to wonder away from the bulls eye in Double action mode although its not as bad in single action mode. The weapon is accurate when held steady though. The ammunition is fairly hard to find locally but is available from various sources on the internet for about $25 per box, plus shipping. recoil is almost (Above picture courtesy of Wikipedia) non-existent, especially when compared to a
modern firearm. The rounds are almost anemic in regards to power. They will still kill you, but they have nowhere near the power of a 9mm or even the .38 caliber. Still this is one of my favorite pistols due to the unique action and ammunition.
