MCarbo is good stuff, but not as refined as CGW…Mine has MCARBO spring kit in it and is 1.5# SA. Factory was just over 3# on same scale.
I've got both in my CZ's. If you are getting the entire package with hammer and such CGW is awesome (but a lot more $$). However, for just springs I've been using MCarbo in everything else. Shadow 2, 97b, and PCR all have MCarbo springs. MY 75b Omega has the full CGW kit installed. I haven't played with recoil spring weights to see what that does on the CZ's.MCarbo is good stuff, but not as refined as CGW…
