Ok. I have found that it is easier to explain this with a picture:
http://home.comcast.net/~jmaia5/firearms/1991a1t.jpg
I have a Colt 1991-A1 series 80. I installed a "drop-in" Chip McCormick grip safety and hammer. Now, here is the issue. When the gun is in condition 1 (cocked and locked, as in the above image), if I apply pressure to the hammer as illustrated by the black arrow (without touching anything else), the thumb safety disengates (as shown by the white arrow). I suspect this might be something to do with a part being out of tolerance on either the grip safety or hammer, as this did not happen with the original factory parts. This requires maybe 3 pounds of pressure to accomplish. This is also why I have a holster with a thumb break. On the off chance that I accidentally disengage the thumb safety, I don't want a gun sitting in a holster at condition zero with nothing in the way of that hammer.... Anyone have any ideas what else might be going on? Is this a problem with the McCormick parts that people have maybe encountered in the past? I'm waiting to hear back from the tech people at Chip McCormick to see what they say, but figured I'd post it here as well......
