CZ USA 91763: Cz-usa CZ 75 SP-01 Accu-Shadow (CZ Custom) Discontinued. The Shadow platform has been known for accuracy and the new Accu-Shadow takes it to the next level. The Accu-Bushing system holds the barrel with much more precision enabling us to cut group sizes nearly in half. In testing the pistols returned groups substantially less than 3 at 50 yards (using Fiocci 124 Jhp). Add to that a full complement of custom work including competition hammer lighter springs (11 lb. recoil 13 lb. main) thin black aluminum grips stainless steel guide rod and polished internals. A short-reset disconnector is used to greatly reduce trigger reset between shots making this DA/SA trigger reset like a nicely-tuned single-action only trigger. The Accu-Shadow is topped with a fiber optic front and Hajo serrated target rear (adjustable for height also drift adjustable for windage). Short of a full custom pistol it'd be difficult to find greater out-of-the-box accuracy than the Accu-Shadow can deliver.
