Alyx's Gun

"Alyx's Gun" is the nickname given to Alyx Vance's trademark weapon in Half-Life 2 and its Episodes. It is an average sized, easily concealed pistol with a 25-round magazine housed in the grip, and is capable of both semi-automatic and automatic fire. It is probably a mini machine pistol like the one used by the Sniper in Team Fortress 2.

Since the actual name of the pistol is never given, it is possible that Alyx made the weapon herself, as it is quite unique in design, but it resembles an SMG1. Though it is unknown what kind of ammunition it fires, it does roughly the same amount of damage as the Pistol, so it's possible it uses the same ammunition as it, 9x19 mm, which would be why the clip is so small.

Alyx is the only NPC ever observed using the pistol. The player never acquires it in normal gameplay.

Tactics
During the first two chapters of Episode One and a brief period in Episode Two; the player is unarmed, with only the Gravity Gun, and has to rely on Alyx to dispatch enemies, depending on the availability of physics objects to use as ammunition. Alyx is a fairly good shot, but the player must not leave her to deal with too many enemies by herself, or she can become overwhelmed.

Alyx seems to have unlimited ammunition for this weapon.

Trivia



 * The weapon is a modified M1911, as is made evident by the weapon's grip, and chamber section underneath the modifications. The breach has been modified to hold the SMG1's chamber and firing mechnism, including the autmoatic pin, and barrel cooling, to cope with the new fire-rate.


 * The barrel of Alyx's Gun looks somewhat similar to that of the SMG1, though shortened greatly, making it possible that it is a heavily modified SMG1. Close examination reveals that it is bulkier than an SMG and has a slightly different texture along the barrel.


 * Alyx's Gun is a usable weapon in various mods, including HL2:CTF and SMOD.


 * The gun can be equipped if the player uses the console command "give weapon_alyxgun", although the model will display incorrectly, as it will apparently be floating in mid-air and is facing the player. (Proved by equiping the gun, then setting viewmodel_fov to a higher value)


 * Although there is a console command to give the gun itself, there is no simple way to get ammunition, unlike most of the other weapons from using console commands. The player can however, spawn an enemy holding the gun, which will allow the player to pick up ammo as they would normally from a dead enemy.
