You ask good questions and I enjoy talking about this stuff.maybe I ask too many - you're probably about ready to test your pistol on me!!
hammer and trigger - O1 steel - - - do you heat treat them or just use the steel as it comes from the factory??
Spring steels - could you offer a discussion on you opinions - 5160 is probably the most famous - used in car springs for a hundred years - you don't seem to be too fond of Brownell's - 1095 is your second choice, but, it's given to you, it appears, by a friend. What's your best choice and why??
I thought the tempering temperature of 666 was interesting - - - the 'number of the beast' - Revelation 13:18 - wanna address that? (or am I opening a can of worms??)

The 01 is soft and easy to work and is also precision thickness. It saves me the trouble of surface grinding to arrive at a standard thickness. As is its too soft to work in the sear area and would quickly round off with use resulting in "hair trigger" or wont cock at all so therefore it needs to be hardened and tempered. Some gun makers will case harden mild steel with great results but I like the O1 because I can grind it and shape it after its heat treated. Case hardening is only a few thousands thick and can be ground through in a heartbeat.
5160 is a good steel for springs but I have come to love 1095 for these pistol springs. Dan always keeps me supplied with his scrap 1095. I machine and grind the spring to finished size and heat it in my Even Heat oven to about 700f and dip it in PBC anti-scale and ramp it up to 1450 for about 3 minutes and very quickly quench it in Parks 50 oil. Then cool my oven down to 666 (667) will work, to temper it. It only needs to soak for about 30 minutes or so. Next the spring needs to be sanded and polished before tested. No stress risers or nicks are allowed because thats where it will break.
666 is the devils number and easy to remember. No bible thumping here but I am always thankful to God when a spring works.
