I send everything that's not plastic or aluminum.  That includes barrel, hammer, sear, everything.

Careful on an egw hammer.   They are now warning not to nitride their hammers.  They can break.  Ask me how I know.

That's what I'm curious about. I'll have to email egw and get their thoughts as a lot of my internals are egw

I've had EGW hammers that weren't nitrided and had very low round counts break at the spur.  Problem is with the design and the amount of material removed,  not the nitriding.  I still use them though.

They have beefed up the spur.  The nitride makes the thin parts brittle.  I wonder about the nitrided sear noses though...

Nitriding is a surface treatment and does not make parts brittle if done correctly.  My sears are nitrided and are holding up just fine.  If you're worried about it, then don't send those parts.  Or call H&M and ask them.  If there are any concerns, they'll give you an honest answer.

I was under the impression that the nitride process involves temps upwards of 1000 Fahrenheit.  I don't know what the implications are for the thin metal at the tip of a sear nose.  I've got several nitrided sears and they seem to be fine.
