I have a G35. It has a reduced power firing pin spring, extra power trigger spring, extended striker/firing pin, and glock minus connector. All springs are zev tech. Its about 2.5 or so. The firing pin safety and spring stock.
The only issue I have ever had with this setup- Gun started doubling during a USPSA match. Upon dis-assembly I found the firing pin safety spring had turned sideways not allowing the firing pin safety to return to position therefore allowing the firing pin to flow back and forth. I believe that this error was self induced during reassembly the night before. Stopped, Put it together right. Before then and since then, thousands of rounds problem free.
