These triggers are very high quality triggers and have the double knife blades. The triggers will operate by either set position or unset position. The front trigger swivels forward to hit the sear, or you set the rear trigger and it is activated by pulling the front trigger. Triggers are made with good quality springs and the rear trigger is made as the originals were, with a flat piece that push on instead of pull back. Plate is 5 ¾” X 7/16”. Highly styled.
