Controls
The SPHINX is decocker-only while the CZ can be converted back and forth between decocker and safety (for “cocked-and-locked” carry), and ships with the parts needed to do so. On both pistols, these controls are mirrored on both sides. With the hammer fully cocked, pressing down on the decocker lever will safely drop the hammer to a half-cocked notch as in the top right photo inset above.
In both cases the slide stop and magazine release are not ambidextrous, although the mag releases can be swapped from one side to the other.
Trigger
Here’s where we get into the first CZ 75 comparison, because the SPHINX uses the traditional CZ 75B trigger mechanism and FCG design while CZ seems to be moving towards its simpler, possibly stouter, and better-out-of-the-box Omega system.
I like the shape of the new P-07 trigger — carried over from the P-09 — a lot. Not just in looks but in how it feels. The SDP has a more traditional curved trigger, although it has a great side-to-side radius to it and the subtle vertical grooves feel nice. In this case I do prefer the CZ.
