I'm not an Omega owner, but the consensus is that the standard non-Omega action can be made better than the Omega. That is why the Competition models like the Tactical Sport, Shadow Series, TS Czechmate, etc. are not Omega.

This recent thread has many comments about CZ's, and might be of interest. Wanting a really accurate 9m/m.

If it might be a carry choice, and you'd prefer not to carry cocked-and-locked, then a decocker model saves you from having to manually lower the hammer on a loaded chamber.

They are good shooters and odds are you'll like one, or more than one.
