from R.E. Davis. The double knife action makes this trigger ideal for a hunting rifle but can be adjusted for a very light pull for use on the target range. The triggers extend 3/4" through the plate making them a great choice for Pennsylvania and Kentucky style muzzle loading rifles as well. The rear trigger is wide and comfortable to set and the front trigger has a slight curve. Excellent quality. 5-1/4" long, 7/16" wide. Well finished, properly hardened and dependable. No. 53ST12
