Kimbers are nice. But when i got my ultra carry last year i had an enormous problem with it failing to return to battery. when i called and spoke with one of their armorers i was told to put an imense amount of lube on it and to that i needed to shoot it approx 750 to 1000 times to break it in. And then if it continued to have failure's i could send it back for them to look at it. No other brand of firearm do i know of that you have to put $350 worth of ammo through it before you can bet your life on it. needless to say yes i put a case of ammo through it and it worked itself out but no longer felt comfortable carrying. those failures were in the back of my mind so i sold it .i basically broke it in for someone else! dont get me wrong im not trying to down kimbers they are sweet, but if i called glock, springfield, ruger, smith and wesson or Sig sauer with that problem they would have wanted it back to prevent their customers from being disgusted with their product
