With the trigger-guard off and the action out of the Stock, the  Krag trigger can be pushed forward to release the striker mechanism.
(When assembled, a normal Krag Stock and Trigger-Guard prevent this forward movement).

Note:
The Krag Safety, when engaged, holds the Striker Mechanism in the rear 'cocked' position and the Bolt is 'locked' closed. The Trigger can be pulled, but, the applied Safety keeps the Striker from moving forward.

If something should hold the Sear out-of-engagement with the 'tensioned' Cocking-Piece, the mechanism will 'Fire', when the Safety-Lever is moved to the 'Off' Position.

If the Krag Trigger/Sear Assembly is free to move and function normally, the Striker Mechanism would make contact and be held back by the Sear. An accidental release' would not occur.

(My second photo has the sear held out of position. A little more movement of the Safety to the 'Off' position will release the Striker with enough force to potentially fire a cartridge).
