The .223 pistol is a truly unique weapon of which only one specimen, obtainable by completing a specific quest, exists in the whole game. Its damage per shot, range, and armor penetration (courtesy of a special Perk) are unmatched by any other non-energy handgun in the game. The small magazine is its only shortcoming. Having SMG animations, the weapon can be given to Katja or Ian.
Here, the .223 pistol is no longer a one-of-a-kind firearm, being available for purchase in many a store and encountered in the hands of many criminals in post-War Northern California. In absolute terms, this weapon is more powerful in Fallout 2 than in the previous game since the .223 FMJ round was made armor piercing in the sequel.
Combined with the pistol's Weapon Penetrate perk, the favorable DR modifier of .223 FMJ results in this gun being less affected by armor than any other single-shot Small Gun in the game. It averages 25 HP per shot on unarmored targets, and 13.64 HP on the best armor in the game.
Though bested by a few among the whole slew of new weapons introduced in Fallout 2, the .223 pistol remains a powerful handgun with a reasonable range and a very reliable damage output against any type of opponent. Its low ammo capacity remains its main weakness.
When this weapon was carried over from Fallout 1 into 2, the developers neglected to change the description. While in the first game this was indeed a one-of-a-kind weapon, several of them can be found throughout the game in Fallout 2, making the description a bit ironic.
The .223 pistol, despite being labeled as a pistol, uses sub-machine gun animations. This prevents certain characters, like John Cassidy or Vic, from using it, but allows others like Sulik and Katja to do so.
In the WORLDMAP.TXT for random encounters, the .223 pistol is referred to as an autoloader.
This pistol's appearance is modelled exactly after Deckard's handgun in Blade Runner, right down to its double triggers and red LEDs.
The .223 pistol was planned to be included in S.T.A.L.K.E.R.: Clear Sky as an easter egg, along with the Bozar and generic .223 ammunition, but only remains partially implemented in the game's resources.
