The Universal Hammer Spur Extension by Carlson's is an easy way to increase the ease of use for nearly every firearm with a hammer. The extension is ambidextrous and features knurled ends for a positive grip. Installation is quite simple: slide the extension over the hammer and tighten the set screw with the provided hex wrench. Overall length is 1.5" long.
The hammer expander will require minor fitting to clear the frame at full cock on Henry, Marlin, Rossi, Winchester and other new models with cross bar safety
