I was having similar issues with my Kimbers. FTF, FTE, and failure to go into battery. One is an Ultra carry (3") with a ramped barrel and the other a pro carry (4") without a ramped barrel.
I tried Federal FMJ, Cor-Bon PowRball, and several others without success.
Here are what has worked flawlessly:
Golden Saber (std & +P)
Winchester T-Series (std & +P)
Hornady XTP
Federal Hydra-Shox
I now carry the Winchester T-Series 230gr +P without hesitation. I practice with them and the 230gr std loads to be certain of reliability. Cases are available online for rather reasonable prices to make it worth while to use for practice.
In my HK USP45 and my Para 1911, I have not had any ammo issues at all. So I shoot whatever in them.
