You are correct, interesting to see it is the same as the K12, it is a cunning trigger blade and I like it a lot as it allows you to place your finger where you like without trying to constrain it. The same reason why I like the Putter trigger.
The next change they made was to get rid of the lever for compressing and just put a PCP cylinder on the thing, if you have the instruction book you may find it shows this version. If only there was better tech cover here we would see more K12's on the firing line at competitions.
