I was glad to see your forum. I own four Kimbers and have yet to have a failure of any kind. Nor have any of the MIM parts disintegrated like some would lead you to believe.
I did have a problem with my last Kimber, a Super Carry Custom HD, but it's not a failure issue - I posted a thread about that.
Actually Tangle is my dog's name - she just let's me use it. When I first got her, she kept herself or her leash tangled around my legs, so she got the name Tangle.
