The GrovTec US Inc GTHM79 hammer extension for T/C Arms Contender is a practical upgrade for shooters working with scoped setups or simply looking for better hammer control. When a scope or other optics sit close to your action, reach becomes awkward—the stock hammer can be cramped to manipulate. This extension solves that problem by adding horizontal reach and a larger contact surface, giving your thumb or hand something substantive to work with when you need to cock the gun or manage the hammer during reload or clearance checks.
Built from black steel with the fit and finish GrovTec is known for, this hammer extension mounts directly to your Contender and can be positioned on the right or left side to suit your shooting style. Installation is straightforward for anyone comfortable working on their firearm; no guesswork required on fit—this one is engineered specifically for the Thompson Center Contender platform.
That platform-specific design is important: GrovTec hammer extensions are not universal, and this one is sized and shaped only for the Contender. Do not attempt to fit it to any other firearm. If your gun spends time behind glass or you simply prefer the control and confidence of a larger hammer face, this is the kind of accessory that pays dividends on every shot.
