Update:
I installed the Zev Fulcrum. The trigger feels lighter and better but not a dramatic change in mushiness but its a Glock and its fine. The important part is that I can dry fire without jerking the gun all over the place. So far an improvement !
The new trigger feels way nicer on the finger
I will try it on the range soon.
Is it worth $257? All in all it comes with a lot of parts... if you add up all the springs, ejector block, disconnect that it comes with its not a bad deal over buying all the parts individually (of course there is also no need for that ..)
I have not yet adjusted it
