The SA-459 combines the smooth cycling action of our dual valve system with the comfort and control of an ergonomic pistol grip, for sure handling and comfort during high-stress situations. These models are designed to shoot heavy loads. it features a rubberized pistol grip which puts the trigger hand in perfect alignment for shooting from a seated position. For fast target acquisition, the 22 barrel is nimble and delivers its tight charge through an extra-full fluted choke tube. The SA-459 has a bright green fiber-optic bead for a true aim, but also has a removable Picatinny rail for a scope, so missing isn't an option.
