Fits like a glove - Nighthawk Custom Drop-In 1911 Threaded Barrel

True drop-in fit in my Springfield Armory TRP. Zero modifications needed! Barrel to slide locking lugs, barrel link and barrel bushing were perfect. I checked the barrel lug to frame contact and the slide stop pin was not binding. The TRP barrels are factory fit and matched so I was a little surprised that it fit as well as the factory barrel. No feed issues or out of battery issues when fired.
