Thanks. I think I may want to perform that kind of surgery on this gun. It's a stainless Kimber gold match and the channels for the trigger bow are very rough, like sandpaper. The scoring on the trigger bow looks like it was made with a coarse abrasive. I'll see how long the grease job lasts, and if it's tolerable, then I'll just keep doing it. If not, I'll try the surgery.
