Li'l Devil (Little Devil) is a unique weapon added with the Fallout: New Vegas add-on Gun Runners' Arsenal.


Main article: SIG-Sauer pistol

A large framed semi-automatic pistol, the SIG-Sauer 14mm autopistol was imported alongside matching 14mm ammunition to the U.S. in limited quantities.[1][Non-game 1] This powerful weapon and its ammunition was relatively uncommon, and could be rechambered to accept other, more common high powered cartridges.[Non-game 2]

A Sig-Sauer autopistol rechambered to use 12.7mm ammunition, this variant has a seven-round capacity. Similar to the 14mm pistol, it has good stopping power, but has wider spread and higher skill requirements than most other pistols.[Non-game 2]

Compared to the standard 12.7mm pistol, Li'l Devil does greater damage, fires faster with a higher damage-per-second (DPS) value, has a greater critical chance and critical hit damage multiplier, has a lower AP cost and has less spread.

In terms of appearance, it has a shorter barrel, two instead of three vents, a black synthetic grip, and a matte gray finish. Unlike the standard 12.7mm pistol, Li'l Devil is considered a holdout weapon. Like most unique weapons, weapon modifications cannot be applied to it.


Li'l Devil can fire a total of about 595 standard rounds, the equivalent of 85 reloads, from full condition before breaking.

  2. 2.0 2.1 J.E. Sawyer's Formspring, 4th June 2012: "why didn't you use 14mm instead of the 12,7mm?"
    "Making it 12.7mm helped gun people intuit that it was effectively .50 AE."
