ROCK ISLAND ARMORY 1911 A1

Overview

****USED firearm please see photos for detail****The Rock Island Armory 1911 A1 10mm with 6-inch barrel is a modern, hard-hitting interpretation of the classic 1911 platform, built for shooters who want increased velocity, extended sight radius, and the powerful performance of the 10mm Auto cartridge. This model features a full-size steel frame and slide, giving it a solid, recoil-dampening foundation that helps manage the 10mm's energy. The standout 6-inch extended barrel boosts ballistic performance, typically improving muzzle velocity and delivering flatter trajectories-making it especially well-suited for hunting, metallic silhouette shooting, and backcountry defense applications. True to the traditional 1911 A1 design, it maintains a single-action trigger system, grip safety, and manual thumb safety, offering a familiar and proven control layout. The extended slide also enhances sight radius, improving precision for longer-range shots compared to standard 5-inch 1911s. Ergonomics remain a strong point, with the classic checkered grip profile that naturally points well and provides a secure hold during rapid fire. Most variants include adjustable or high-visibility sights, and many are optics-ready or easily customizable thanks to the 1911's vast aftermarket support. Built by Rock Island Armory, this 1911 A1 in 10mm is designed for shooters who want a rugged, no-nonsense pistol that blends old-school reliability with modern stopping power. It's a practical choice for those who prefer the 1911 platform but want significantly more energy on target than traditional .45 ACP offerings. Overall condition excellent. -AB
