I had a similar experience with a Kimber. Here's the thing I've found about the 1911 platform: Don't deviate from the original specification unless you're prepared to deal with these kind of feeding issues. The 1911 is a good platform but it was intended to have a full slide length, 5" barrel, and tolerances that would support combat operations. When manufacturers try to down size the frame to make them more attractive to the concealed carry market they are hurting their reliability. This certainly isn't an absolute but it happens often enough to where I would never recommend a down sized 1911 to anyone that isn't prepared to deal with reliability issues.
I'm not singling out Kimber necessarily but there are plenty of posts out there from disgruntled Kimber owners. There are also a bunch of Kimber owners who will tell you they've never had a problem with theirs. Both conditions are true.
