I am happy to announce that my conversion is complete and the pistol performs flawlessly.
For those of you who don't know, I converted my Cougar 8040 from an "F" model (de-cock/manual safety) to a "G" model (de-cock only). This was my first time doing any gunsmith work at all, and I consider this conversion to be quite easy.
If anybody would like to convert their Cougar to a "G" model, I'd be happy to assist.
Now I just need to order my checkered rosewood grips...
