Ruger's American Compact pistol has a pre-tensioned striker system that features a powerful striker spring for positive ignition without a heavier trigger pull. It has a rigid, one-piece, precision-machined, black nitrided, stainless steel chassis with integral frame rails and fire control housing. Its modular wrap-around grip system is for the adjustment of palm swell and trigger reach to fit a wide range of hand sizes. Ergonomic grip modules lock in solidly and do not loosen. The American Duty also features Novak LoMount Carry three-dot sights, ambidextrous slide stop and magazine release, Picatinny rail, and non-slip surfaces on its side and grip.
