The Chinese pistol can fire a total of about 1250 rounds, the equivalent of 125 reloads, from full condition before breaking.
Zhu-Rong v418 Chinese pistol - While the Zhu-Rong does the same base amount of damage, it is unique due to the fact that it fires incendiary rounds, which deal fire damage over time.
Sim version - A simulation-only version of the weapon which differs primarily in health, with item HP so high that it is essentially non-degrading. This version also has a slightly different appearance, lacking the rust found on various parts of the standard weapon.
Chinese Dragoon Pistol - A cut version of the weapon is included in Operation: Anchorage, apparently intended for use in the normal game after completion of the simulation. This version has identical stats to the Fallout 3 version, but has the same appearance as the simulation version of the weapon. This version is not used anywhere within the add-on and can only be acquired through the use of console commands.
Republic of Dave - one can be found in the Museum of Dave, though it must be stolen.
Cryo lab - one can be found in a storage room here, on a table surrounded by other wasteland objects.

The full name of the weapon in ancient Chinese characters can be seen in the texture file. They are inscribed "Type 17" on the left hand side of the pistol, while the right side is marked "民國十八年晉造; Republic Year Eighteen, Made in Shanxi." A number "1861" also appears but it can't be the date of manufacture since the Shanxi Type 17 was produced in 1929 and the Mauser C96 in 1896. The Republic year/民國 on the pistol is actually the abbreviation of Republic of China/中華民國, which is the Nationalist Chinese government that retreated to Taiwan after they lost the civil war in 1949. It's most unlikely that is should appear on a Communist Chinese weapon.
The weapon model has no firing pin.
Fallout: New Vegas includes a brief appearance of the Chinese pistol, seen on the far wall of the "hidden" weapons room in Mick & Ralph's. This version of the weapon is a non-interactive static mesh (i.e. a decoration) rather than a working weapon. Most of the other resources for this weapon remain in the game's files, but no actual, working version of the weapon exists within the game itself.
