Gary, one of the drawbacks in the Hiwall set trigger system is the fact that when you fire it the rear trigger has to "Fly" upward and smack the Sear to disengage it from the Hammer and let it go. This is time lost. The second issue is Sear drag. The Sear is actually riding on the outboard radius on the back surface of the Hammer. That is why there is a fly in the Hammer in order to keep the Sear from re-engaging in the half cock notch.
This drag has got to have an affect on Hammer or lock time. In a plain trigger Hiwall when you break the Trigger in firing you will continue to pull the Trigger back and keep the Sear completely off the Hammer. I believe JD and I had this conversation many years ago on the old Schuetsen MSN site when he did his testing. As a result I did some bench UGH! testing and got results much like his although I did not test as extensivly as he did. Well enough. HTH Regards, FITZ.
