SIG-Sauer was a pre-War company that manufactured weapons.
They were based in Switzerland and Germany. Their only known manufactured weapons are the 14mm pistol, the P220 Sig Sauer and the 12.7mm pistol.
The SIG-Sauer 14mm pistol appears in Fallout and Fallout 2. Another product, the P220 Sig Sauer, appears in Fallout Tactics. Additionally, the 12.7mm pistol appears in Fallout: New Vegas.
Behind the scenesEdit
The real-world SIG Sauer corporation never produced a 14mm handgun, nor a weapon that looks like the 14mm/12.7mm handgun from Fallout.
