I bought the Kimber Micro 9 Crimson Carry to take my CCW test with and then carry. Took it to the range shot 200 rounds after cleaning it. not a hiccup. I have been back to the range 3 times to shot have used my cheapest 9mm ammo that I had, still no problems. I love this gun my Rock Island Armory 9mm is going to be sitting in the safe I am afraid, it is a nice gun but it is not a Kimber.
