Solid upgrade - GrovTec US Hammer Extensions

This hammer extension was a nice little upgrade to the Henry model X I own in .357. It seemed awkward in the photos, but once installing I found the extension to allow much more ergonomic manipulation of the hammer. On this rifle, hammer control is the only safety available. I found the part to be delivered exactly as shown, however in some photos this appears to be a pack of 4-6 hammer extensions and it's not clear in the description that you only get one. I'd also mention the fit and finish. This does fit very well on the hammer but it could use a tumble in some abrasive media to knock down the burrs. It's got a couple of sharp edges from machining that I chose to file down and re-blue. Had it not been for the burrs, I would give it 5 stars.
