Christensen Arms strives to craft the finest 1911 handguns ever produced, and the new A4 and A5 aluminum-framed 1911s are no exception. Currently available in 9MM, each frame is machined from 7075 billet aluminum and assembled using only premium components, including a tunable match-grade trigger. After being machined, each newly-designed slide is hand fit to its frame to guarantee a perfectly smooth and highly accurate handgun – a 5-shot, 2 inch group at 25 yards. Weighing in at roughly 2 lbs, the new A4 is the lightest 1911 we produce.
