Just left the gun store after handling a new gen 4 G17. It seems the trigger is alittle stiffer than my gen 3 gun and I was wondering if I can put in a gen 3 trigger/trigger bar in it to smoothen out the trigger pull. I think it is that damn dimple on the side of the trigger bar that is rubbing on the slide that is making it feel alittel stiffer than the older gen 3 guns? Is this possible???
