I have not had any in the shop with any problems. You may want to contact Kimber and find out if it is true and if they are offering a free fix. Taking safety parts out of a firearm opens you up to major liability if there is an accidental shooting with your firearm or even if you shoot someone in self defense. Best to get if fixed if there is a problem.
Good shooting, John K
Anyone worth shooting is worth shooting more than once!
Stop crime, shoot back!
