In September 2012, Nighthawk Custom started using only parts that they developed in house. These parts are all fully machined from solid billet. Billet parts are widely known to be much stronger and more reliable than other manufacturing methods, and Nighthawk offers nothing but the highest quality parts to their customers.
Titanium firing pins have been used for years to decrease lock time. Nighthawk Custom machines their firing pins for precise fit to prevent primer flow. A titanium firing pin is a great upgrade to your 1911.
