I have a Sprinco recoil system for the CZ-75B/75 which came with a gun I bought used.
Seems to work, but it's a bit like gilding the lily, as most 9mms (and a full-size steel-framed CZ is heavier than most) arguably don't have enough recoil to justify their use. Note: If someone has health issues, like arthritis in hands or wrists, or similar problems, THAT may be justification enough.
I'd offer you my Sprinco unit at a BIG discount, as it's been setting unused for 7-8 years, but I realize that probably won't work: as you're across the pond from me and import/export issues will get in the way.
None of these systems really reduce recoil -- they just change the recoil experience, stretching or shortening the recoil impulse in ways that some shooters find more tolerable or appropriate for their purposes. (Some competitive shooters use these and other devices in conjunction with other parts or methods to allow them to shoot lighter loads, or to speed up slide cycling, etc.)
If too much felt recoil is an issue, you might get similar results by trying different weight recoil springs. Wolff Springs -- if you can get stuff from them directly or indirectly -- offers a recoil calibration pack, and I think they also have a variable rate spring that changes the recoil experience. STIFF recoil springs are a pain, and I try to avoid them.
For most guns (a heavier recoil spring isn't protecting the gun, no matter what load you're shooting.)
