Our Fixture is made of 7075 Aluminium with hardened decking rods and drill inserts for drilling sear and hammer holes. The fixture is used for two operations, drilling holes and lowering the frame deck height. You need to drill your sear and hammer hole first to get your staring dimensions before filing. Once you have your starting dimensions you can then proceed to hand filing the deck height to its final dimension. We have discontinued the smaller fixture and no only offer the large one. This fixtures will accommodate all single stack frames.
