A resettable and reusable auto-injector with a trigger is presented where the trigger (32) has a pivot axis (P) dividing an elongate body into a distal portion and a proximal portion, where the proximal portion has a finger surface on an upper section and a bearing surface projecting downwardly configured to engage a button blocker (26) to function as a safety feature to prevent premature firing of the auto-injector before the needle hider is pressed against an injection site.
