As an earlier poster mentioned, a lot of stuff on the internet gets "magnified." I'll add, that it also becomes "gospel" from the keyboards of lots of folks who've never had one.
I'm old enough to remember that a generation ago everyone wanted a Colt . . . but Colts rarely "worked" right out of the box and a whole industry sprang up of "custom" gunsmiths and parts makers to remedy the problem.
I had Colts back then too . . . for they were the best going. Still, they had their problems that had to be addressed.
This all being said, Kimber has had good and bad years, like most automatic makers. After shooting loose a nice, tricked out Colt Combat Elite from the mid-80s, via tens of thousands of practice rounds and lots of competitions, I replaced it with a Kimber and have had zero problems with the Kimber for eight years or so now.
BTW, that nice ol' loose Colt WOULD jam every time you put one of three magazines I had in it . . . and a fourth, a vaunted Wilson magazine would sometimes jam too. That being said, it was virtually impossible to jam the Colt with any other magazines I used in it. (Magazines are a huge problem that get's blamed on the gun sometimes).
However, if one wants to have a firearm with literally zero problems . . . buy a revolver! Yeah, they may not look "cool," but when that gang banger yanks out his Lorcin or Jennings and tries to shoot you and the gun jams, he won't be laughin' much longer!
I'm not really a Kimber fan, though I like the company, and mine's been wonderful. No, call me the S&Wfan . . . wheelguns, that is!
