Just picked up a 35 year old gun that may not have been shot, cleaned or lubed in as many years. I want to take the trigger group out but it is stuck. Note, I did remove the pin that holds the trigger group in place. Someone recommended that I try some "penetrating oil" and recommended Kroil, a product not in my cabinet.

I do however have some WD40. Will this qualify as a penetrating oil? Will it hurt a blued steel receiver?

What is the next step if the trigger group will not come out. Give it a light tap with a wooden dowel and a hammer?
Heat the receiver with a heating pad?

Thanks

Lou
