Not saying anything against a Ruger MkIV
But the true beauty of a "Conversion Kit" over a seperate, whole Pistol (i.e. a MkIV), is the added Trigger Time you get on your Host Lower
Same Trigger Pull, Reset, etc
Not having ANY experience with the "Shadow 2 KADET", I can't speak to ITs accuracy
BUT, knowing the CZ75 KADET; its design lends itself to make IT, a VERY accurate Pistol
There are several Members here that have ditched their other .22s, and now compete with their KADETs
Go back and watch some of JoeL's Videos with His KADET
Very impressive !
