The installed threaded barrel is a key upgrade on this Nightmare Full-Size. It is bushing-fit, measures approximately 5.6 inches, and extends past the slide, with a knurled thread protector included. The factory case label notes the standard 5.0-inch spec, highlighting the extended length on this example.
The pistol retains hallmark 1911 controls and sighting features: single-action only operation, a single-sided thumb safety, a beavertail grip safety, and fixed three-dot dovetailed sights (front blade with a single dot, low-profile rear with two dots). The slide uses an external extractor and has rear cocking serrations only.
Ergonomics and handling details include a non-railed Government-pattern frame with a straight heel (not Fastback), checkered front strap and mainspring housing, and black checkered grips with SIG SAUER logos. The finish is matte black on both slide and frame for a uniform presentation.
Performance-focused parts include a skeletonized, lightened trigger and a skeletonized commander-style hammer. Capacity is 8+1 in .45 ACP, and this pistol ships with five 8-round magazines for immediate range readiness.
Supporting documentation and packaging details add clarity: the factory hard case carries the model label 1911F-45-NMR, the packaging label is dated 30-SEP-2018, and the case indicates U.S. manufacture.
