Standard Manufacturing's S333 Gen 2 Thunderstruck is a double-action .22 WMR revolver built around a paired-firing design: each deliberate pull of the trigger fires two rounds from the eight-shot cylinder, so a full cylinder gives four pulls. Barrels are 1.25 inches, overall length 5.5 inches, weight 18 ounces. The grip is polymer, the sights are fixed, and the finish is blue and black. An articulated trigger safety and a transfer-bar system are built in to guard against unintended discharge.

It is sized for concealed carry and that is the use Standard Manufacturing names, with fixed sights intended for close-range defensive work. In Connecticut carrying it means holding the state's pistol permit, and buying it means being 21; there is no fixed waiting period beyond the dealer's DESPP authorization. There is no magazine, which removes one variable from the purchase. The 18-ounce weight and 5.5-inch length are the carry figures that matter.
