I picked up a used Zev Technologies gen3 G17. Everything is good on the gun except the trigger pull. It comes in at 5.75lb. I swapped in the 2lb striker spring that was inluded in the package and it only reduced the pull weight by about 1/2lb, but it caused intermittent light primer strikes. So back with the 3lb spring and have been shooting without functional problems in ~500 rounds. I really want to improve the trigger weight. I called Zev and the tech assumed I had the v4 connector, and recommended replacing it with their latest Pro model or the Glock(-) model. when I asked if I could use a Ghost connector he tech said he wouldn't mix the parts from different brands. Looking for some input from the board on this issue, mainly if it's safe to use a Ghost connector in the Zev trigger. I am leaning towards the Pro3.3 or the EVO Elite. The gun is exclusively for range sessions and matches. Thank you in advance for any advise and recommendation.
