The GrovTec Hammer Extension (brand part number HM71) is a steel hammer spur extension built specifically to fit the Browning BL-22 and Astra 357, giving owners of these lever and revolver actions a larger, easier-to-reach hammer for faster manual cocking. Made by GrovTec, the extension is machined from steel and finished in a blued coating that matches the factory look of both host firearms. It is designed as a direct, model-specific fit rather than a universal clamp-on part, so installation keeps the original hammer geometry intact. Shooters who find the factory hammer spur too small to reach quickly, especially with gloves, get a straightforward upgrade with this extension.
