Underhammer trigger

[Columbus]

Quite a few years ago I bought this HA underhammer for a relative and it's come back into my possession. The trigger sear(?) was broken and the gun would not stay cocked. I ordered two new triggers and springs and it works fine now but it's probably going to happen again. The half cock notch causes it. If you don't pull the trigger firmly all the way to the rear it will catch every single time. The trigger is cast and it just fractures off. The spur/sear is a really deep notch on the trigger - would you grind it off, try to find machined parts or what?

Personally I have ground it down some to make a smaller notch. I had the same issue of it breaking and broke a couple. Grinding down seems to have helped. The metal does seem brittle.YMMV.

You can cut about half off the safety notch and then taper and round off the back side and yes, I've broken the trigger nose by pulling very slowly.

I almost forgot, it was many years ago. I called Deer Creek and they sent me a new trigger & hammer free but that was back when they were selling H&A kits. They said that they had gotten a bach of triggers that were too hard and broke easy.
