Sounds like it is kind of hit and miss with the Kimbers and I guess I am just lucky I have a TLE and a Stainless Ultra Carry II both have not had any problems.
I have 800 rounds through the Ultra and I shoots really well. My wife is an excellent shot, she can do a 1.5" group in the center of the target at 7 yards with almost anything she shoots. She shot my Ultra a couple of range visits ago and put 7 rounds in the center of the target, 3 of the shots went in the same hole on the target, she moved it back to 50 feet and did a 4 inch group there. This is almost as good as she is with her Glock 34 or my TLE.
I would recommend this gun to anyone.
