The Diamondback .45 ACP 1911 pistol with 5" barrel and adjustable sights is a modern take on America's most proven fighting handgun. Built on a full-size frame in domestic stainless steel, this silver-finished 1911 combines proven Series 70 single-action reliability with practical upgrades that don't mess with what works. Whether you're training at the range, competing in action shooting, or carrying serious firepower for home defense, this Diamondback gives you the classic 1911 platform with the refinements you actually want.

The match-grade 5" barrel delivers the accuracy 1911 shooters expect, paired with a 6.5" sight radius for precise sight alignment. The ported slide reduces muzzle rise without gimmicks, while custom engraving adds character without sacrificing function. Novak adjustable sights let you dial in your zero, and the skeletonized aluminum trigger breaks cleanly at 3–4 pounds. The fire control system uses wire EDM and micro-polished tool steel for consistent, reliable ignition.

You get three Chip McCormick magazines loaded to 8+1 capacity per mag—serious ammunition for a serious gun. The G10 composite grips provide confident purchase in any condition, and the gun ships in a Pelican 1200 case with foam protection. At 38 ounces, the silver-finish stainless steel construction balances shootability with durability. This is a 1911 built for shooters who know the platform and don't need marketing—just results.
