The Browning 1911-22 isn't a full size 1911 with a barrel conversion kit. It's built to 85% of the scale of John M. Browning's original 1911 pistol in 45 ACP. Designed with a sense of duty and precision, and copiously tested to ensure accuracy, function, and the feel you should expect from a pistol bearing the Browning name. This model is about as modern as you can get, made with lightweight composite materials, a 1913 Picatinny accessory rail, skeletonized and lengthened components for lightweight and better ergonomics.Features: High strength, lightweight, A1 compact polymer frameIntegrated 1913 Picatinny railBlack laminated and stippled grips with checkered front strapCommander hammer, beavertail grip safety, and extended slide releaseComposite frame with machined 7075 aluminum subframe and slide railsRust-resistant steel barrel
