I have a Cape Gun and the rifle side has a single set trigger. To make a long story short when I got it the spring had been broken and welded and broke again, I had a new spring made years ago. The lock now fires a round when the trigger is used unset, but when it is set it does not fire. The firing pin is loose, not binding. The set is very light - my question is - do I screw the set screw in or out to give the set trigger a heavier pull.
Second question is - is this likely or not to change the ability of the lock to fire the cartridge when the trigger is set?
Obviously, I know little or nothing about how these things work.
For what its worth this gun was made in Stettin, Germany (now Poland) sometime between 1885 and April 1, 1892.
