This is conversion of my own FO3 Mod to TTW that changed the Chinese Pistol from "FO3" into a Fully Automatic Weapon ".5mm Beretta .10mm Uzi",
but has now been remade as a 9mm Machine Pistol for TTW that is a Single Handed Fully Automatic Pistol "Since NV used 9mm Ammo for the Chinese Pistol" .

REQUIREMENTS
TTW "Tale of Two Wastelands"

Notes
this Mod comes in two varieties for the first one the vanilla Chinese Pistol becomes the 9mm Machine Pistol meaning that enemy's can also use it as well as the player, it can be bought, found on a enemy, or you can use the code to get it XX004325 XX is for load order for me it is 0A004325.
The Second Mod alters a separate Chinese Pistol from the DLC02 "Anchorage" that applies to the Player Only "AFAIK" and you can get it by using the code XX003F41 XX is for load order for me it is 0B003F41.   

Install
Extract the .esp file into your Fallout NV Data Folder load Fallout Mod Manager "FOMM" and check the box next to
TTW 9mm Machine Pistol.esp for version 1 and click Launch NVSE to play the game, it effects every Chinese Pistol in the game so you can buy it,
find it, or already have it. I personally would hate to encounter an enemy who has it but that can happen too.

For the Player Only Version do the same as above except check the box next to TTW 9mm Machine Pistol Player Only.esp

Replaced Main File with Version 1.1 makes both as 9mm Uzi, not .9mm and set as Player Only for PO version.
Just download the new file the old one is gone.

Update Version 1.2 made it as a 9mm Machine Pistol to save on confusion. lol
