I haven't  found and extra size pins for an Old Colt with .170 pins.  Anyone out there make the pins out of 17-4 that are over sized?  I have pin guages I could use to measure accurately if someone could make them at a reasonable cost.  Or is it just better to buy a cassette trigger?

Geissele makes triggers to fit the old large pin Colts. You might want to call them and see if they will sell you a set of pins.

I don't know about 17-4 but KNS sells oversize (.170) pins.
Now with more political fatigue.

They don't sell as well as they did, but they're still available. I'm not sure there were many places to get them from 17-4, even back when Colt was being actively anti-social. Hmmm... sounds like an interesting little lathe project... I'm assuming .170 pins are actually .170"?

I have K & N .170 pins in it now.  They  mike at .170.  Waiting for a couple of pin guages to come in, in addition to what I  have now.  You are right.  It's  probably a lathe project.  I found .188 pin stock in 17-4 stainless and C2 Tungsten.  Those would have to be turned down and polished to fit.  The 17-4 pin stock was 5 times higher than the Tungsten.   Thanks for the info.
