I have a G23 G4 with about 1500 rounds through it and the last time I was at the range I noticed the trigger was getting pretty gritty. I cleaned it good when I got home and looked at the safety plunger and cleaned it well and put a drop of oil on it and put the gun back together and have done a lot of dry firing. I have thought about changing the trigger assembly to the Apex 102-115 ultimate kit with the polished safety plunger. Does anyone have any experience with this trigger system and if so could you give me your two cents worth? Any input would be appreciated.
