Heat treating the trigger bar

bob2ovi · 09-25-2015, 12:24 PM

On my original shooter the metal in the trigger bar in the area of the sear is rolling up where it contacts the firing pin. This happened about 50 shots ago. I stoned the burr down, but it is now back. The metal can be cut with a file so this time I plan on re-hardening it with kasenit and quenching in oil. I have 2 questions. Should I draw the temper after the kasenit? Also any ideas on why this happened? The firing pin looks good, and as far as I know the firing pin spring is original. I have some spring stock and could try a lightened spring if you think that would help.
