    Gunsmithing Required On most production pistols the barrel will drop in and work without any fitting; however, there may be some minor fitting required due to tolerance stacking. The fitting area will most likely be the bottom barrel lugs. You will need to remove just enough material so the pistol goes fully into battery.

    The Nighthawk Custom line of Fully Machined parts are designed to be the gold standard in the 1911 parts industry. All Fully Machined parts have been fully CNC machined from solid steel billets. We never use cast, metal injected moldings or polymer parts. In order to create the World’s Finest 1911s, only the best materials can be used. That is why you can trust Nighthawk Custom Fully Machined parts in your 1911.

    All Fully Machined parts are backed by a lifetime warranty.
