Kahrs are 95 percent cocked.
I have a P9 so I got it out and did some measurements.
Immediately before the striker is released to fire, the striker spring is compressed about 13mm. About 10mm of that is done by the slide preloading/pre-cocking, about 3mm is done by the trigger action.
Looking only at the striker spring compression in terms of compression distance indicates that the preload accounts for about 77% of the total compression.
Spring force is a function of the square of the compression distance, so to find out how much force is on the striker as a result of preload vs. trigger action, we have to do a little math. It works out that the last 3mm of cocking action by the trigger accounts for about 41% of the force that the striker spring will exert on the striker.
So, depending on how you want to look at it, the Kahr striker (at least for the P9) is either about 77% cocked (spring compression distance) or about 60% cocked (spring force) when a round is chambered.
For comparison, Glocks are 50-60% cocked (spring compression distance) or about 25% cocked (spring force) when a round is chambered.
