Scarlett,
I was directed to your thread after I posted a thread titled 'SP-01 manual safety sear cage rebuild'. Basically, it was a plea for help as I was rebuilding my SP-01 with the CGW 75105 kit and could not for the life of me figure out how to rebuild the sear cage.
After having to reorder 3 new lifter springs from CGW (2 extra as cheap insurance) having lost the first one (or as CGW site says, 'L-spring... often lost, seldom found', delphidoc directed me to your sear cage disassembly and reassembly video.
I took the laptop to my work bench in the garage so I could pause after every step. One note, camera angle is great, but I had to zoom in to make sure I had everything oriented as you did. Long story short, I got it together on the first try, though not easy with my fat fingers. Basically, you were guiding my hands.
I could not have completed this upgrade without your video. I finished off the build and holy cow! A completely different gun (didn't think perfection could be improved, but CGW and CZ Custom have figured out how to improve the triggers on an already amazing firearm).
From your other videos now you've got me thinking about other changes, such as firing pin block removal (does this improve trigger feel?) and the single action only trigger. I already upgraded to the 85C trigger (my finger never like the curvature of the stock trigger).
Thanks again,
Dave
