I should have my hammer spring tuning pack from Wolff on Thursday.
With the stock spring, and as measured by my ancient RCBS spring type trigger pull gauge, my trigger is consistently dropping at 4.75 pounds. The break is getting smoother with each range session. I've had it out twice now, for a total of 406 rounds.
Out of the box it has a better trigger than my CZ 75B. None of the hammer camming you see on the 75 in single action mode.
I have had the odd failure to extract/eject. When I came back from the last range trip I popped the extractor out and there was a lot of caked on goo in it's recess. Way more than the round count would predict. I cleaned it all out, so we will see how it goes next time.
Over all I am liking the thing. If it pans out as I hope and expect, a set of Meprolight night sights will be the next addition.
