I ordered this kit and the floating pin, given I wanted to changed the clothes out on my "Barbie Gun" and figured it was an opportune time for an upgrade. As shallow as it sounds I decided to try MCarbo solely based on a few reviews and Chris' Rockwell 50 statement of OVERKILL...hard as axe head. A la Tool Time grunt worthy.
So...I changed things out with relative ease with some help from Chris' video on the CZ 75 and some others like https://www.youtube.com/watch?v=DS15MpW0B_c
Between all these guys made it easy for a newbie like me to get the job done right.
Check pull pic attached, I was amazed how light the pull got, so I checked and triple-checked and took the highest reading. Wicked reduction and still shoots fantastic. Only thing I dislike about the Shadow is the "adjustable" mag release button. As you can see, the new one is just sitting there, since for some reason they loctite /stake the screw for what is an adjustable screw that is butter soft. Great gun and easy to modify and work on.
