Made from aircraft quality 7075-T6 Aluminum. Ambidextrous. Fits standard Encore, Pro Hunter, G2 Contender, and G1 Contender frames with a serial numbers higher than 19600. Semi gloss black anodized finish. Pro Hunter frames do have a “swing” hammer spur. The spur swings 45 degrees left or right rather than a full 90 degrees. This can feel a bit awkward and/or uncomfortable on your thumb when cocking the hammer. This hammer spur extension can be mounted on either the left or right side of the hammer spur and will give you a more comfortable 90 degree angle.
