Get quicker, easier access to your hammer with this easy-to-install hammer extension. The lightweight, balanced design will not interfere with the use of sights or scope. Ambidextrous for right or left-hand shooters. It fits T/C Contender and most exposed-hammer rifles and handguns. Available: Black, Silver (not shown).
I bought one and installed it. It fell off the hammer within one week of light use. I have found out that it is made of soft aluminum, not hardened steel.
Summary: 1) too expensive 2) cheap soft aluminum 3) not reliable for everyday use
