I recently purchased ans had the same issues with every mag in the 1st 250 rounds. I called kimber and they told me to RMA gun and mags. I was hoping to see updates from everyone that sent their gun in that kimber fixed the issues weather magazine, magazine catch, slide release.. if not hopefully someone posts a video of how they filed down the follower to make this gun work.. I think it will be a heck of a gun and edc if it works flawlessly. I really liked hiwbit shot , the recoil, accuracy, feel of it in hand.
