These include the standard Government Model, which features a 5-inch barrel, and the Commander, a shorter version with a 4.25-inch barrel for easier concealment. Other variants may include different calibers, such as .45 ACP or 9mm, and various finishes like stainless steel or matte black. Additionally, there are specialized models like the 1911 A1, which has improved ergonomics and sights, and tactical versions equipped with rail systems for accessories.
