Jim- yes its a pain to remove that plug to get the pin out! Bad design I agree.
Here is a pic of my pin...maybe someone already took the piece off so that it isn't necessary to take that plug out to remove the pin? Will it work like that? Doesn't look right to me for a usable gun. Not sure what a 2-piece pin would look like? Can you point me to a drawing of that Colt pin? thanks.
We live in the greatest country on Earth- always be thankful!
