GrovTec GTHM74 Hammer Extension for Marlin Post 1983 Lever Action Rifles

The GrovTec US Inc GTHM74 Hammer Extension is a steel, black finish accessory designed to enhance grip, control, and contact surface on Marlin lever-action rifles produced in 1983 and later, including the 39A, 39M, 1894, 1894C, 1895S, 336C, 336T, 375, 444S, and Glenfield 30A models. This horizontal hammer extension provides improved leverage and a larger contact area, making handling easier in high-stretch scenarios or when mounting optics where clearance can be an issue, while maintaining a clean, integrated look with the firearm's lines. Crafted from high-quality steel, the extension is built to withstand rigorous field or range use and can be mounted on either the right or left side to accommodate the shooter's preferred hand and setup. Each hammer extension is model-specific to ensure proper fit and reliable performance, and it should be used only on firearms listed in its fit guide to preserve safety and function. With its understated black finish and precise engineering, the GTHM74 blends compatibility with durability, offering shooters a practical upgrade for improved control and confidence during rapid-fire or precision shots.
