Shooter45 - The special auxiliary 'bounce reducing' sear spring found on 70 and 80 series Colt Gold Cups is so incredibly minuscule that it is quite easily overlooked and/or lost. Thanks to my son, I do not currently have a Gold Cup on hand to disassemble for a picture, but I did find a superb blow up diagram of the sear assembly on the M1911.org forum. Go to http://www.m1911.org/full_technic.htm
and select the "Special Sear Parts in Gold Cups" link selection about half way down the page for the diagram. Enjoy.
