Half-Life 2 Silenced Pistol (from Half-Life 2 Survivor)
The original view and world models came from Half-Life 2: Survivor
I decompiled the models so it could use the original Half-Life 2 pistol texture instead of his black custom one, i only imported the silencer textures.
I also fixed a bug in the world model that was probably a result of the decompilation process.
What you see in the video is NOT a reskinned version of the original HL2 pistol, it is its own weapon entity (weapon_survivor_pistol_silenced) that acts like the HL2 pistol (weapon_pistol) but I removed the line that manages the muzzleflash.
