The 'D' spring took the DA trigger pull weight from over 10 pounds down to about 9 pounds. SA from 5-1/2 pounds to about 4-3/4 pounds. Polishing took the 4-3/4 SA down to 4-1/2 pounds and maybe the DA down just a bit.
It's noticably smoother and it feels like it's got less stacking near the break point than it did when it was stock.
All I wanted was smooth and about an 8 pound DA with no less than a 4.5 pound SA. I got the 4.5 pound SA and it may not be possible to lighten the DA further without reducing the SA also, so I'm pretty happen where it is.
I did receive the standard and reduced power Wolff trigger spring units and I will try both of them just to see. If the reduced power unit drops my SA below 4.5 pounds I'll go with the stock power unit. I should receive a steel trigger from David Olhasso next week and then I can give the trigger springs a try.
This is a SD gun and I'm not going to reduce the over-travel and reset - I want some of that in a defense gun.
Anyway, it was a fun experience. Getting the sear back in was interesting - having done it now, it wouldn't be nearly so interesting or elusive to do again.
P.S.
I did no polishing on either the hammer sears or the sear faces.
