I have owned over a dozen kimbers and a few High End 1911's (Ed Brown KC, Wilson Combat).
Here is what I do to solve those problems.
None of the 7 I own now have any feeding issues what so ever.
Unless you own them and shoot them, you are just perpetuating a rumor. I have read of folks having issues with TRP's as well. But that's all I can say about them as I have never owned one.
