For what it's worth . . .
I have a Kimber Eclipse Target II that has around 1,000 rounds, and has not had 1 failure. I heard a lot of awful things about Kimber on the interwebz, but mine seems to be assembled like a Swiss watch. Meanwhile Springfield seems to be the sacred cow of 1911's. On this reputation, I recently purchased a Springfield MC Operator (which was even more $$ than the Kimber), sent it back twice, and ended up getting a refund. SA said, at this time, they did not have time to QC check another pistol to send out to me, nor did they even have one available for that matter.
