When John M. Browning invented his classic pistol in 1911, he could not have imagined that for over a century it would remain the standard of excellence in the industry and reproduced by almost every arms manufacturer in the world. The .22 LR version developed by GSG retains the 1911's classic look and feel while incorporating exciting new technology and updated safety functions to meet today's rigorous standards. Every GSG-1911 features parts that are 80% interchangeable with mil-spec 1911s, a threaded steel barrel, and a guaranteed single-action five pound trigger pull. An ambidextrous thumb safety and an extended beavertail grip safety combine to provide two levels of protection. The Target model features hand-filling, molded target-style walnut grips and a low-profile adjustable rear sight and comes with five interchangeable front sight blades. A two inch Picatinny mounting rail is integral with the frame for accessory mounting. Aluminum three-hole trigger. Combat hammer. Rear cocking serrations. Only commercial grade .22 LR HV ammunition with a minimum of 1250 FPS is recommended.
