The back edge is making contact is how I?ve seen it demonstrated. Also the striker is just sitting in a neutral position when the slide is off the frame. Remember the striker is pulled back under tension sitting in a cocked position on the ledge of the sear when the slide is on and cycled. It is held back passed the red arrow in your picture. There is a lot of things going on that engineering designs in that we don?t see with the gun all together in battery. In the end though if you are not confident in the system there are tons of other good options out there. David
