The Grovtec US Inc GTHM72 steel hammer extension is a practical upgrade for shooters running Ruger Blackhawk revolvers, H&R Topper shotguns, and New England Firearms Handi Rifles. If your hammer's spur is hard to reach or uncomfortable to cock under gloves or in the field, this steel extension adds leverage and reach, making the gun easier and faster to operate when it counts. Built from steel for durability, it's the kind of no-nonsense part that improves handling without changing what your firearm does.
Grovtec has been making American-made gun parts since the late 1980s, when founder Bob Grover started in the machine shop building recoil pads and scope covers. That hands-on manufacturing background shows in their approach: solid materials, straightforward design, and a focus on real-world utility. This hammer extension follows that same formula—a simple steel component that gives you better control over the hammer on single-action and break-action firearms.
Installation is straightforward for anyone comfortable doing basic gun work. Minor fitting may be required depending on your specific hammer's dimensions, so if you're not confident working on your own gun, have a gunsmith handle it. Once fitted, it becomes part of the firearm's personality—the kind of upgrade that makes you wonder why you waited so long.
