I’m confused. 1 and 1/8” at half cock seems plenty.
The 1and 1/8" half cock would make it easy to get the cap on the nipple but it is also a
hammer fall that can fire the gun if the sear is broken by bad handling or if the tumbler fails.
That nipple cover is the cure and I had COMPLETELY forgot about that idea.
That lock need to be redone with another tumbler or a reoriented hammer.
One thing just crawled out of memory. Several years ago a man bought a long range rifle
with one of my "4 pin" locks on it that had been altered by filing or grinding off the normal
full cock notch and then altering the half cock so the lock could be fired from that position.
It shortened the hammer drop but rendered the rifle unusable because of no safety of any
kind.I made and installed a new tumbler with two positions and a "fly".I think there are rules
that apply to these guns in competitive shooting involving a working lock.
