Ok, so YES - the Shadow 2 Kadet will fit a 75 B frame...BUT...
- the dustcover needs to be fitted, it is too wide - made for the Shadow 2 frame. Some filing and lapping compound with a mallet...30 min.
- the Shadow 2 Kadet is LONGER than the SP-01 Kadet...so if you buy the CZC SP-01 Kadet compensator you need to open up the inside OD so it can accomodate the longer barrel...this took me 90 min.
It shoots great, but even with the contoured firing pin (per the suggestions on this forum), clipped firing pin spring, and up to 16# hammer spring - I got light strikes with CCI MiniMag.
I plan on trying again with CZC lightened FP spring, and a 17# hammer spring.
I am using a CZ 75B with FPB removed, short reset, and race hammer.
Will post pics soon, I am getting it Nickel Boron plated since it is aluminum, I want to make it last...
