This mod lets you instantly swap your dominant hand from right to left or left to right with a single hotkey. By default, press R to switch hands on the fly — no menus, no delays. The keybind is fully customizable, allowing you to change it to any button you prefer (e.g., mouse side button, F, V, or any other key). Perfect for ambidextrous players, quick tactical adaptation, peeking around corners, or simply personal comfort during long gaming sessions. Works in real-time without any performance impact.
