i bought a ultra carry II and had failure to go into battery approx 2 out of every magazine, called kimber got told to put massive amounts of lube on it and run 500 rds through it. should not have to buy a $800 gun and put another $150 dollars worth of ammo through it before i can trust it and have it dripping with lube, but i did, after 500 rds only have about 2 failure to return to battery per 100 rds, with hollow points have no malfunctions what so ever. dont unload it at a gun show just puts the problem on someone else. I would go to the range with a video camera and have someone video the firearm malfuntion multiple times. then send it with copy of video to kimber and ask that they replace the weapon being at this point it is a lemon. I have other kimbers and my brother and father do as well and not had one issue with either of them from being brand new right out the box. they do make some nice guns just an occasional lemon like everything else in this world. might have been assembled on a monday after the gunsmith had a long weekend of partying!
