Thanks for the pics OP.....looking at them I'd say the thumb safety was broken prior to you pulling the trigger. The little flat you see (in 2nd pic) on the internal stud of the thumb safety is what blocks the sear when in safe position. It is a close tolerance fit and any mis-alignment can allow hammer to drop. Saying that, a new thumb safety is typically a part that is fitted to every pistol so you need a competent 'smith to fit a new one or send it back to Kimber.
Curious as to the history of weapon.... Did you recently acquire it? Have you fired it much lately (prior to the AD/ND)?
Has it been dropped?
This is a good reminder for everyone to visually inspect their weapons frequently and more importantly to perform safety function checks periodically too.
