The majority of european medieval crossbow ‘s in later middle ages used a long trigger “lever”, running directly on the roller nut. The lock trigger was fitted into a metal notch (sear) in the bottom of the nut to protect the nut form being grind away by the lever.

The trigger was assisted in locking into the sear with a leaf spring or round spring.
