Tybee is shot twice in the shoulder -- the blood spots are large and plainly visible -- but there are no bullet holes! Guess the wardrobe department didn't want to permanently damage the shirt.
No explanation for why Tybee is back using his arm so quickly. He took two big slugs in the same shoulder. That shoulder would be destroyed. One is enough to break the joint, the humerus, or sever the subclavian artery. And two just doubles the chances for severe injury and much slower recovery, if the initial injury is fatal. Shoulder wounds are not a minor thing.
