Jim62, Thank you for the info on the Browning 1885 trigger system. I have personally not been "inside" one, so your info gives me a little better understanding of the system. I am contemplating installing the McGee mod in my 1885 high wall. I will not set it for a trigger pull of less that 2 pounds.
Glad to report what I found. I bought at least 10 of the 1885 Brownings, High wall, BPCR and Low walls from about 1996 to 1999.
I tuned several of the triggers and was sort of astounded at how cheesy made the trigger blade itself was compared to that super hard all steel sear.
I ran an 0-80 Allen screw diagonally up through the trigger into the sear notch so I could adjust the engagement without permanently cutting the trigger sear insert down..
Once I adjusted the trigger fairly creep free, it was sort of scary how often I had to adjust it for more engagement due to the wear. A gunsmith friend of mine tested the trigger sear insert with a set of Rockwell files and he said it was about as hard as key stock from the hardware store. That is about what I thought when I worked on them.
