Nighthawk Custom 1911 Government Barrel Features The Nighthawk Custom Government Barrel is fully machined from premium-grade 416 stainless steel engineered to be the gold standard for 1911 pistol accuracy. Every barrel is slightly oversized in the lock-up areas by design ensuring a gunsmith can achieve the tight precise fit that produces Nighthawk Custom s renowned accuracy rather than settling for a loose drop-in fit. The barrel is threaded .578x28 at the muzzle for 5.75 inches overall giving pistolsmiths a solid foundation for a threaded Government-length build. Heat treatment to 40-44 HRc hardens the steel against wear from repeated cycling while preserving the dimensional stability needed for match-grade accuracy. Nighthawk Custom subjects every barrel to multiple quality-control inspections throughout the machining process a standard that reflects the same scrutiny applied to complete Nighthawk Custom pistols. The barrel is not ramped and is not a bull barrel keeping it a straightforward drop-in match component for standard Government-frame builds rather than a specialty configuration. Because gunsmith fitting is required this barrel is best suited to pistolsmiths and experienced 1911 builders rather than a true plug-and-play swap. For shooters chasing the accuracy Nighthawk Custom pistols are famous for this barrel delivers the same quality control and material standards in a component built to be fitted into an existing Government-frame 1911.
