One of the first things I did with my Super Carry Pro was to install a Wilson extended slide release followed by a Wilson flat wire recoil spring. No more paper clip required to break it down. I keep all the original parts I replaced on my Kimbers in plastic bags marked with the guns they came from. In the event (god forbid) I ever had to return one to the factory it will go with the original parts so the warranty isn't voided. Kimber can be a real stickler on that and they have been know to change guns back to original state and charging the owners for doing it whether they wanted it done or not.I installed ambi safeties on a couple of my Brownings. They can make a huge difference. I just installed a Wilson extended slide release on the Kimber. The doubled sided safety may well be next on the list.
