The 1911 Fastback Carry Nightmare pistol features a stainless steel frame with rounded grip and mainspring housing. Each pistol is built using premium internal parts including a match grade barrel, hammer/sear set and trigger. The all Nitron coated frame and slide is contrasted with natural stainless controls, barrel bushing, extractor and grips screws. The Nightmare is finished with a set of black G10 double diamond grips that makes this 1911 Sig Sauer looks as good as it performs.
