I have an article which appeared in "Rifle" magazine, issue #107 for Sept-Oct-Nov of 1986 which shows you how to modify a stock trigger including making it fully adjustable. It's very well written with photos and diagrams explaining the step by step process. I'd copy and post if for you DIY folks but would be concerned about copyright laws and "permissions to publish".
I don't know if the magazine is still in circulation. The article was written by one Richard Aldiis. It might be archived somewhere in the internet. The title was "An Adjustable Trigger for Ruger's 77/22".
