I've had one Kimber, a 4" Pro Carry. Bought it new. Very accurate, but I could not depend on its function. I shot it enough that I replaced the spring at the recommended time, so I know it was broken in. It would not feed 230grn hardball, or any other 230 grain cartridge. It had to have something with a shorter OCL. Settled on 185 grn hp and Wilson Combat magazines. (The Kimber magazine was awful.) Anyway, the thing still jammed about one time in every 5 or 6 magazines.
I sold it for almost what I paid and bought a Ruger SR9c. I can't make the Ruger jam. It just won't. No malfunctions since I took it out of the box. I know my 124 grn. +P+ rounds are still less potent that the .45, but at least I know for sure it will fire. I can say the same thing about a Sig.
I think a person must have some knowledge of 1911 upkeep to keep one running right. I've only had 2 in my life that worked out of the box, which I think a new gun should do. One was a 70's Gold Cup and the other was a 5" Springfield mil-spec.
