Made some updates
I was going to take my time with this, but my excitement got the best of me.
Upgrades and modifications:
- Conversion to SAO
- Removed Firing Pin Block (CGW sear cage spacer in place of lifter arm)
- CGW Ring Hammer
- CZ Custom SAO Trigger, CGW reduced power trigger return spring, CGW trigger pin
- Polished all internal contact surfaces and extractor, feed ramp, chamber (had a couple FTE's, Wolff extra power spring on the way)
- CZ Cocobolo thin grips and SS screws from CZ Custom (not totally sold on these. I'm kinda digging the rubber ones, as nice as the cocobolo ones look)
The results were amazing. The trigger breaks clean and light, there is almost zero take-up and about 2mm of reset and total travel. Trigger is 1911 like, and that's about as fine a compliment as I can give as far as triggers go. Everything went together without a hitch for the most part. I had a few hiccups with the trigger not resetting because the trigger bar spring jumped off it's track and wedged itself between the trigger bar and frame.
My trigger bar was very, very poorly machined and the groove was cut off center and extremely rough. Attempts to smooth it out apparently made the track a little less distinct and the spring wire liked to jump out of the groove. I solved this by putting a little bend so the part of the wire that contacts the trigger sits off the frame a little and it seems to have solved it. If not, I may have to re-cut the groove.
Other than that, I had some FTEs after about 300 rounds or so. I think the packing grease in the extractor groove started fouling the extracter. I took it apart and cleaned it all out, it was filthy in there for just 300 rounds. I polished everything per the FAQ in the gunsmithing section and hopefully that solves it. I also have a Wolff extra power spring on the way in case it happens again.
Anyway, I couldn't really be happier with how this all turned out. Just need CGW to finish those fancy new adjustable sights and I'm going to call her done.
