The Anti Freeze attaches to most of our standard thumb trigger models while the Main Squeeze attaches to the new whisper series. Both accessories provide an allowance of movement before firing the release. Simple draw and anchor then smoothly push into the accessory without fear of an unexpected shot; thus no reason to be tentative. The smooth cycle the accessories provide help result in an unanticipated shot. All of these accessories are machined aluminum with steel mounting screws.
Please note: The thumb and palm shoes work on MOST thumb trigger models, but not on the Chocolate Addiction series.
