Terry, I agree the up and down controls seem backward. My Kimber has it done in the traditional manner. I would do like Johngoboom and after decocking, I'd click off the safety. This is when you are taking your time and concentrating. So later when you need the gun in a hurry it is just squeeze the trigger and let the double action be your safety. You just need to get used to the double action being all that is required for safety. DA revolvers have no safety and no problems needing one.
Mightybig, I'm not a gunsmith but I believe you are safe to sand with 400 sandpaper lightly back and forth lengthwise of the guide rod and then finish up with 600 sandpaper, clean and lightly lube. If the scars are shallow you can remove them but if they are deep you can smooth them some and it will be better than prior to your work. Don't sand around the rod as this is not how it moves in the gun. I believe that return spring has a larger diameter hole on one end. This larger end goes into the frame and the smaller end will tend to scrape the rod as it slides on. If it is ever assembled backwards and you move the slide, a deep scar can occur on the aluminum rod. Easy to do as they look the same size.
