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.

Later, between 1450 and 1500 a more complex 2-axle lock appeared. It allowed a crispier and easier trigger pull resulting a more accurate shot. The 2 axle lock disadvantages were an increase in the loading speed.
