I have a Gen 4 G23. I would like to clean up as much of the take up in the trigger as possible. I would also like to sharpen up the break while keeping the total weight no lighter than four pounds. I'm going to polish all the contact surfaces, but my big questions are: What do people use for the polishing? Jewlers rouge? Mothers Metal Polish? The plethora of connectors and springs has my head spinning. How do they work together and what do I need to accomplish the above trigger feel and weight?
