yes the trigger in the picture in the book is drawn wrong. ive just had a good look at the trap that i have in my hand and i can now see where i went wrong.yes you are right, the spring has moved through 90degrees whilst springing, my apologies. Been a long time since ive used the body grip, now use fenns. cheaper and i get on better with them. Taking nothing away from teejaa, still a good bag.
