‘MASTER LINK’ DERRINGER. NON SHOOTING CONCEPT: Firing pin and trigger/ hammer geometry

Got back my interest to this project.
First :
Made a sprang firing pin that does not interfere with closing of the bridge like the free floating one did.
Second:
Got an idea of a trigger and hammer relationship - perfect circles geometry. I don't think I have seen this anywhere. SHOWING JUST AN ILLUSTRATION, THE REAL HAMMER /TRIGGER WILL HAVE THE ENDS SHAPED IDENTICAL TO THE WASHERS
I believe the release will be nice.
Also I finally decided about a single spring between the hammer and the trigger/ sear for simplicity and cleanness.
It has to be a torsion spring I may need to make.( I ruled out flat or compression springs. )
But it will be in the next episode(s)
Thanks for watching.
