In Feb, CGW quoted 2-4 weeks wait time until I could ship, then 8-10 for the work. I ended up sending that pistol to CZC, and had it back before CGW notified me that I could ship my pistol in if I wanted.
I could not be more pleased with the work CZC did. Side by side comparison, I believe the trigger feel is a hair better with czc. Blasphemous I know.
For home gunsmithing, I think CGW is the way to go. Their kits are completely idiot (me) proof.
It is great to have two solid options. Take your pick and you will be more than happy with either.
