Remember, the Canik sear housing (what they call ejector module) is 100% a copy of the Walther. Since it's a copy, Canik can't by magic having a better trigger. So how can it be better feeling than the Walther? Firing pin block spring.
I guarantee the Rival/Mete with the claimed "better" feel trigger is 100% because Canik's copy of the Walther sear housing uses a lighter firing pin block spring. That's why Canik had the Severe Duty recall that only changed the firing pin block spring starting in 2019 but still live on their website. Someone could easily prove is that the FPBS on a Canik is lighter than a Walther PPQ, Q, or PDP, I just know I don't have the tools to measure it.
Since the Walther PPQ that the Canik is proven trip the sear at a hard hit at the back (why Canik states the recall happened), I don't know if Canik is accepting some level of danger or they found the exact right sauce for safety that Walther will not update in their FPBS.
I don't doubt the Rival has a better feel, but since the return spring is 100% interchangeable by the Walther and Canik (Springco/Overwatch 2 "red" and "green" springs are marked Canik and Walther) and they share the same design trigger bar that carries over P99 function, it's the FBPS without question that is the difference in "feel." The return spring is what controls the weight.
Because of the Walther sear design in the PPQ can be trip and because the gun doesn't fire thanks to the FPB...either Canik is perfection for weight or there is a cost for drop test that they publicly failed before.
